German start-up is looking for partners and investors to further develop novel active, electrically sterilisable air filters for health protection




German start-up, with expertise in the production and functionalisation of graphene and its processing into various formulations, is looking for investors and operators of large public facilities. They offer novel active air filters with smart components for stationary and/or mobile applications. Long-term cooperation could take place in terms of financial or joint venture agreements.



The German company is a growing technology-driven materials start-up, manufacturing and selling a portfolio of large-flake, few-layer E-Graphenes (electrochemically exfoliated graphenes) and formulations, tailored to integrate seamlessly into downstream processes.

Spin-out of Technical University they generate revenues selling tailored E-Graphenes, custom formulations and R&D projects to EU, US & JP corporations, SMEs and institutes in the packaging, electronics, wearables and aerospace sectors based on their own IP. Main application areas currently are inks (for conductivity, diffusion barriers and anticorrosion), resins & rubber additives (for reinforcement and antistatic properties) and foams (mainly for air filtration). To overcome capacity limitations and serve the growing demand they have recently moved into new labs and are setting up pilot-scale facilities. By providing good scalability and yield, low production costs and a good processability, their mission is to unleash the currently limited potential of graphene in various fields.

The development of highly porous, conductive hybrid materials is based on a long-term collaboration between universities and start-ups from Germany.

Preliminary tests have already shown that the filter properties of these materials are very similar to those of conventional HEPA (High Efficiency Particulate Air filter) filter systems and that these highly porous materials can be heated up to 400°C in just a few milliseconds, due to their electrical conductivity. In a first test, this effect could already be used to sterilize a material loaded with bacteria.

With the concept and idea, the start-up addresses the following problem: Today's filter materials are passive, i.e. they are based on a purely physical separation of contaminants from air and therefore have to be replaced regularly. If this replacement is not carried out regularly, or if bacterial loads are particularly high and the environmental conditions are unfavorable, conventional filter materials can also act as breeding grounds for bacteria and viruses and, accordingly, can even spread germs via air conditioning and ventilation systems.

Potential of the solution:
The approach represents a paradigm shift in air filtration by moving away from passive filter elements towards active and smart components. The solution can save energy and resources as well as improve the safety of the air breathed in a sustainable way: with new filter materials that are not only able to passively filter out contaminations from the air, but that can also be sterilized, cleaned and regenerated quickly and with little power via heating, all while being installed in a working system. On the one hand, the number of filter changes can thus be dramatically reduced, on the other hand, it prevents that filters can act as a breeding ground for germs also in applications where a regular filter change is not required.

To finally boost development from concept stage to different steps towards market launch partners, e.g. operators from large public entities, are sought who are interested in support and later implementation of the development and/or investors who see the potential and are able to finance specific development toward market entry.

Partner expertise sought:

- Specific area of activity of the partner: Both stationary (e.g. public buildings, hospitals etc.) and mobile (face masks, cars, public transport) applications are conceivable.
Partners are sought who are interested to implement and finance the novel active filters.

Joint venture agreement:
Partners who operate large public facilities are sought to support the idea in form of a project and to foster the process toward implementation.

Financial agreement:
Beside of this, investors who see the potential and who are interested to finance the project idea to realise the development are welcome.

Advantages & innovations:

Currently, there are only passive filter materials on the market.
The new approach is addressed to the following main advantages:
• saves energy and resources
• improves safety of the air
• easy to clean & sterilize using electricity during operation, without need to disassemble filter units
• possibility for “smart filters” that are able to monitor filter loading status during operation
• sustainable
