09/2019 – 08/2022 – EffiLayers
„Process optimization regarding the roll-to-roll production of novel highly efficient organic photovoltaic cells-EffiLayers“
The EffiLayers project as the successor of Photonflex (2016 – 2019) and Flexlas (2012 – 2015) is focussing on the development, process optimization, and production of flexible, highly efficient, and ultra-thin organic solar cells using a roll-to-roll coating system.
Organic photovoltaic cells currently still exhibit lower efficiency and durability compared to traditional silicon-based solar cells. The qualification of novel and efficient materials, as well as the optimization of the coating application by means of roll-to-roll coating equipment, should contribute to a significant increase in efficiency.
Through wet chemical coating processes, the functional layers are applied in the nanometer scale by using a heatable slot-die and processed with different laser sources (short pulse and ultra-short pulse range). After photonic laser drying and thin-film ablation, the OPV cell is protectively sealed by laser encapsulation with a barrier film. The individual processes are monitored by various sensors, and a process control system is implemented.
In this project, Coatema is focusing in particular on the modification of the entire slot-die application process. The novel swiveling die-module enables a stable process through variable adjustment of the die in the range of 8 to 12 o’clock. A proposed horizontal mechanism for adjusting the die ensures precise adjustment or positioning of the substrate to be coated during multiple coating processes. For a uniform application of the substrate, an electrically heated die is used.
In collaboration with the partners, the new process optimizations of the roll-to-roll production are demonstrated and evaluated for the novel OPV cell.
01/2018 – 12/2021 – Greensense
Sustainable, wireless, autonomous nanocellulose-based quantitative Drugs-of-Abuse (DoA) biosensing platform
Printed electronics is one of the fastest growing technologies in the world. Paper and plastic are two types of flexible materials that constitute key substrates in the development of future flexible electronic devices. On the contrary of those based on more conventional plastic substrates, paper-based electronics, made from cellulose, have the advantages of low cost, recyclability and can be expected to have a significant impact in the reduction of environmental impact of "electronic trash" and in providing new opportunities to the pulp/paper manufacturing industry. Unfortunately, the surface properties of conventional paper are not suitable for printed electronics and, typically plastic coatings based on fossil-oil polymers are applied. From a sustainable point of view, this has augmented the interest in alternative renewable biopolymer films and coatings with similar properties. Among the different alternatives, nanocellulose (NC) based films with strength, high aspect ratio, transparency and low porosity and smooth surface roughness are a promising potential alternative.
In the project GREENSENSE we merge healthcare diagnostics and printed electronics in the form of a fully-integrated biosensing platform using nanocellulose. The biosensing platform with the newly developed printed DoA biosensors will integrate different NC-based printed electronic components (supercapacitor and/or a primary battery as printed energy storage (E. storage), display and NFC antenna) and a single microchip to have energy autonomy, wireless communication and to be easy for the user to read the results. High output printing techniques, such as sheet-to-sheet (S2S) screen printing and/or inkjet printing will be used for the printing of the different functional inks onto NC-based substrates. The final NC-based biosensing platform will be easy to operate, flexible, mass producible, cost-effective, environmentally friendly, disposable, and recyclable and will have low power and energy consumption.

Scale-Up of Printed Electronics Recyclable SMART materials
In day to day products, including labels and packaging, there is a rising consumer demand for smart products, that is to say, objects that are able to be part of a digital ecosystem. Embedding sensors and communications technologies while minimizing the environmental impact of these smart products is a key challenge for the future. The major way of achieving this is to work on the base materials of the electronics components to be embedded in, by providing organic materials instead of rare and toxic inorganic ones when applicable. That is the objective of the SUPERSMART project which will enable the direct printing on paper of sensors, displays and electronics instead of bulk conventional electronics devices. It will make the recyclability of such smart products easy. Lead by Arkema, a world-wide chemical actor, together with Arjowiggins, providing technical papers for printed electronics, leading technical organizations (CEA, FraunhoferInstitute, Joanneum Research), first-class universities (University de Bordeaux and Lisbon) and innovative SMEs (Coatema, Luquet & Duranton), the SUPERSMART project aims at scaling up printable smart materials for the smart and recyclable products of the future.https://www.supersmart-project.eu/

The joint project FLEX-G systematically investigates technologies for fabrication of translucent and transparent roof and facade elements with integrated opto-electronic devices, to allow dynamic switching of the total energy transmittance (g-value) of these elements. Therefore, flexible electrochromic layer stacks are directly applied on ETFE web surface in Roll-to-Roll coating processes. ETFE is a common material used for membrane roofs and facades in event halls, airports or railway stations. A second part of the project deals with technologies for direct integration of large-area flexible solar cells based on organic photovoltaics (OPV) into ETFE membrane elements. The project Flex-G contributes thus significantly to energy saving and energy harvesting technologies in buildings. Flex-G thereby supports the aim of the government to reduce the primary energy demand until 2050 to 50 % through these developments.
04/2017 – 03/2020 – SolGel-PV

In the SOLGEL-PV project nanoscale sol-gel layers for usage in solar cells layers are produced, deposited and structured. They shall be demonstrated in an innovative applications: (i) antireflex structure that uses the Mie-resonance for a better light coupling, (ii) at the backs contact of the first solar cel for a better optical performance and higher adhesion and (iii) as a conducting and adhesive connection layer for a cost efficient realization of tandem solar cells. The layers are deposited by in-line capable methods. The nanostructuring is executed in a roll-to-plate technology.
The project incorporates developments in the material science as well as in the regime of process techniques. Sol-gels will be produced by tailored synthesis for different prototype applications. Additionally, deposition and embossing processes for large scale applications are realized.
The following objectives for the three defined prototype applications are specified: Due to the embossed Mie-resonators in the sol-gels, better properties compared to an iso-textur shall be achieved. The sol-gel interlayer at the backside contact shall lead to a higher short-circuit current density of 0.5 mA/cm² higher than for an Al/Si contact due to the reduction of parasitic absorption. Simultaneously the adhesion will be high enough for a later cabling of the modules. With a connection layer for tandem solar cells a III-V wafer and a Si-Wafer shall be permanently connected to each other with a high transparency (>98 %) and a lower voltage loss (< 1mV).
The developed, innovative and cost efficient technologies as well as the higher energy yield are leading to a higher cost efficiency and brings the involved companies a unique selling point and thus a competitive advantage.

01/2017 – 12/2019 – InTres
Innovative support materials for optimizing current conductors within electrical storages.
To enable the decentralized storage of energy up to electro mobility technology, a continuous development of electrical storage is needed. The research is thereby focussing on the efficiency of electrical storages. On the one hand they must be cost efficient and on the other hand the durability and the performance need to be improved. Previously the research was mainly about cell chemistry. However, the conductive support materials have a crucial influence on the performance and cost of Lithium-Ions batteries.
Within the InTres project the performance of electrical storages based on Lithium-Ions technology shall be improved by a resource-saving application of innovative support materials. The objective is to replace the actual current conductors (Al- or Cu-foil) in the battery cell with 3-dimensional support materials (expanded metal, metal foams, metallic net) as well as to investigate their potential.

12/2016 – 11/2019 – PowderSizing
Process- and materialefficient production of thermoplastic-glass bicomponent fibers for the production of continuous-fiber-reinforced thermoplastic components
The mechanical properties of thermoplastic composites depend on the fibre volume content, moistening and distribution of the glass fibres and thus on the strength distribution. The theoretical performance limit is not completely fulfilled by already available composites based on hybrid yarns or film-stacking. In addition, the coating speed is limited to 100 m/min leading to a low economic efficiency. Therefore, new technologies are necessary to achieve the theoretical performance limit in real industrial processes such that the composites could also be used in aircraft engineering. Currently the semi-finished materials are mostly used in the automotive sector. The objective of this research project is the development of a coating system leading to a speed of 2,000 m/min, by which all filaments inside the composite are equally coated and the economic efficiency is increased significantly.

By this the climate change and an environmental friendly and affordable energy supply are addressable and novel innovative solution can be elaborated. More and more applications in lab scale are showing the potential of this new material class. Nevertheless, the transfer into products fails due to the fragmented supply chain. Thus the material innovations are not leading to product innovations up to now.

08/2021 – 08/2024 – IDEEL
Implementation of Laser Drying Processes for Economical & Ecological Lithium Ion Battery Production – IDEEL
In recent years, lithium-ion battery technology has increasingly found its way into new markets. Due to this the manufacturing capacities of battery technologies will undergo an exponential growth. Particularly in Germany and Europe, low-emission and energy-efficient production of these batteries will play a decisive role in the context of climate change.
The production of lithium-ion batteries is a very energy-intensive process in which more than 50% of the energy costs incurred are attributable to the drying process step.
The convection dryers commonly used in the drying process only indirectly contribute the thermal energy to the material and hold considerable potential for increasing efficiency. Drying by means of diode lasers therefore represents a promising approach to a solution. In addition to increasing energy efficiency, the energy input can be controlled much faster and more flexibly. Furthermore, the integration of thermography-based inline sensor technology can improve the drying process.
The aim of the IDEEL research project is initially to realize laser-suitable electrode formulations as part of material development in order to merge the necessary processes for laser drying on a laboratory scale. Based on this work, further manufacturing processes will be developed and implemented in parallel to the scaling of the overall process, which will enable laser drying for use in industrial production environment. In addition to its consulting activities, Coatema is also assisting the project partners by developing, integrating, and realizing the demonstration of a laser drying system, in order to achieve an industrial level with web speeds of up to 30 m/min and a significant reduction in the space required as well as the energy input in the project.

WaterProof: urban Waste and water Treatment Emission Reduction by utilizing CO2 for the PROduction Of Formate derived chemicals
We live in a time when the amount of CO2 in the atmosphere exceeds the records of the last 800,000 years! In order to mitigate the impact of CO2 on the environment and tackle climate change to protect future generations on earth, carbon recycling is imperative.
Among many industrial processes, the operation of wastewater treatment plants is one of the sources of greenhouse gas (GHG) emissions, especially carbon dioxide (CO2) and methane (CH4), as well as indirect emissions from energy production. The goal of the WaterProof project is to improve the carbon cycle of waste (water) by developing a novel and green biorefinery concept electrolysis process that converts CO2 emissions from urban waste treatment facilities into formic acid and eventually into consumable products such as detergents, fish leather, etc. In WaterProof, 12 European partners including Coatema Coating Machinery GmbH, Avantium Chemicals Bv, Avantium Support Bv, Fundacion Para El Desarrollo y La Innovacion Tecnologica, Fundacion Tecnalia Research & Innovation, Stichting Waternet, Ecover Co-Ordination Center, Nova-Institut für Politische und Ökologische Innovation GmbH, Nordic Fish Leather ehf, IZES gGmbH, Frames Renewable Energy Solutions B.V., NV HVC and Corporacion Centro De Ciencia y Tecnologia De Antioquia bring together their knowledge, experience and technical resources to achieve the project goals.
Coatema Coating Machinery GmbH, in close collaboration with Avantium, plays an important role in upscaling the production of gas diffusion electrodes (GDL) in WaterProof. For this purpose, Coatema will design and develop an appropriate roll-to-roll line by upgrading the Click&Coat pilot line with a high-temperature calendering module and a coating system for suspension coating.

09/2022 – 08/2025 – NOUVEAU
Novel Electrode coatings and Interconnect for sustainable and Reusable SOEC
The demand for green hydrogen and renewable electricity production is growing rapidly. The solid oxide electrolytic cell (SOEC) is a key technology for the production of hydrogen with high efficiency. However, a limitation in the production of SOEC is the high demand for rare earth elements (REE), which is the bottleneck of their mass production. The goal of the NOUVEAU project is to produce innovative and optimized electrode and interconnect materials with at least 30% less La, 20% less Cr content and from recycled sources. This enables SOECs to be manufactured at lower cost with improved lifetime and sustainable by design.
To achieve the goals of the NOUVEAU project, Coatema Coating Machinery GmbH is collaborating with other European partners including VITO, Forschungszentrum Jülich, Marion Technologies, Eindhoven University of Technology, QSAR Lab, IMDEA Energy, CNRS – Centre National de la Recherche Scientifique and Fiaxell SOFC Technologies.
For upscaling the electrode coating process, Coatema will develop a unique dual-slot die system to transfer gradient coating concept into the roll-to-roll process and produce electrodes with optimized microstructure. In addition, Coatema will develop an energy-efficient drying process that combines the traditional convection dryer concept with a radiation-based technology to further improve the electrode manufacturing process as part of the NOUVEAU project.

To extent the service portfolio of the OITB the equipment at different facility clusters will be upgraded and validated in industrial use cases from P&G, SONAE, Huck Folien, Capri Sun, Fiat and I3 membranes. These upgrades will allow the OITB to offer services for advancing new surface functionalities ranging from laboratory validation (TRL4) up to validation in an operational/industrial environment (TRL7).
Within this project Coatema will upgrade four different pilot lines:
- Nanoimprint line at Joanneum Research
- Organic and printed electronics production line at the Aristoteles University of Thessaloniki
- Roll-to-roll ALD system at Fraunhofer IVV
- Modular Click&CoatTM pilot line at the Coatema R&D centre
Together with our partners we will scale up pilot-production processes, enhance the automation, improve the yield and impended new technologies.

03/2020 – 02/2023 – RealNano
In-line and Real-time Nano-characterization technologies for the high yield manufacturing of Flexible Organic Electronics
Organic & Printed Electronics (OE) nanolayers is one of the most rapidly emerging sector of Nano Science and Technology. While the OE market is rapidly growing worldwide, from 31.7 B$ in 2018 to 77.3 B$ in 2029, the industrial manufacturing cannot meet the more extensive commercialization demands on speed, reliability, materials quality, final product efficiency, and stability.
The RealNano project will play a significant role in the digital transformation of the EU industries, with an ambitious aim to demonstrate a yield improvement of up to 90%, in combination with above 30% reduction on wastes and resources for nanomaterials. In order to accomplish this, novel and fast real-time nano-characterization material tools & methodologies based on spectroscopic ellipsometry, raman spectroscopy, imaging photoluminescence, and laser beam induced current mapping will be integrated to in-line R2R printing - and organic vapor phase deposition pilot-to-production lines.
In this project, Coatema is focussing on the mechanical integration of the developed characterization tools and the mechanical improvement of the R2R pilot-to-production line.

02/2019 – 05/2023 – PEPcat
Energy-efficient advanced oxidation for removal of organic substances in wastewater through Plasmonically Enhanced Photocatalysis
The Institute for Urban Water Management and the Institute for Environmental Research at RWTH Aachen University are developing a novel process for oxidative water purification in cooperation with AMO GmbH (Aachen), Coatema GmbH (Dormagen), UMEX GmbH Dresden (Dresden) and HOLINGER Ingenieure GmbH (Merklingen), as well as Beijing Capital Company Ltd. (Beijing, China).
The aim of this project is to increase the elimination of so-called organic trace substances, such as pharmaceutical residues, which are only insufficiently retained in the normal purification process. The developed coating technology which the partners have named „PEPcat“, allows post treatment of waste water effluents via sunlight using almost no energy or chemicals in case of success. During the demonstration project for investigating this plasmonically enhanced photocatalysis with sunlight, experiments will be performed using waste water at the sewage treatment plants in Aachen-Soers and Beijing Dongba.
The special feature of this project is the direct implementation of the small-scale research of PEPcat into the industrial production scale. In this context, Coatema will take over the upscaling of the process as well as the planning of a pilot line to produce nanostructures. By implementing a Roll-to-Plate (R2P) concept, production bottlenecks can be avoided and the future scaling of nanostructuring for even larger substrate areas or for the production of nanostructured substrates can be realised.
The R&D centre project team works with an interdisciplinary team of researchers in publicly funded projects, B2B development projects and internal Coatema research projects. The department's objective is to develop and recognise new developments in the fields of coating, printing and lamination and to drive forward the implementation of Coatema scale-up processes for new technologies and markets.
Both the scope of activities and our portfolio encompass projects in the field of organic electronics, printed electronics, thin layer solar cells, organic solar cells, perovskite solar cells, (thin layer) batteries, electrochrome components, 2D materials, inline analysis methods and much more. Since 2002, we've carried out research projects with a volume of more than 80 million euros in collaboration with more than 110 national and international partners. In the near future, one focal point of our research will be the implementation of Horizon 2020 projects and the subsequent promotion of research in EU Horizon Europe projects. In order to further strengthen the European research region, we are always interested in taking part in new projects. Please don't hesitate to contact us with your project ideas.
We work in the areas mentioned above in collaboration with many international research institutes. The presentation about our research projects provides you with an initial overview of our activities.
