The French company seeks partners interested in using this technology in the framework of a commercial agreement with technical

Full description Graphene is a perfect, defect-free single layer of carbon that exhibits exceptional properties. Various types of graphene are available on the market, with different advantages and disadvantages in terms of purity, quality, and scalability for industrial production. The French start-up, created in 2017, developed a unique and patented process to produce graphene in aqueous solution, thus facilitating the introduction of graphene in a broad range of applications. It clearly set the French start-up apart from the competition, still supplying graphene in powder form, with its security and product variability limitations. The start-up supports industrial companies and R&D partners in their product development projects by developing customized graphene-based solutions compatible with their industrial environment and with minimized environmental impacts. Its expertise on graphene focuses on 3 main applications: - Non-metallic primers for protective coatings, in the building, heavy industry, and transportation sectors - Thermo-mechanical resistance, thermal & electrical properties for composites and polymers, with applications in low-carbon emission transportation. - Energy efficiency (battery management system) Few examples of projects with associated benefits: + 25% in thermal diffusivity for an addition of 0,2% graphene in a structural epoxy resin + 35 % improvement of surface corrosion protection thanks to a graphene-enriched epoxy or aqueous-based paint. + 10 to 40°C in glass transition temperature of epoxys + 10% more hydrophobic varnish The French start-up is looking for partners for commercial agreement with technical support. The potential partner knows the specific market need. The French Start-up develops proof of concept (PoC) and prototypes based on the requirement specified by the partners. The final goal is to integrate the graphene technology in the partner production manufacturing process. The French company will test as well as adapt the technology to the partners’ needs.

Advantages and innovations This disruptive production process is the result of 10 years of R&D efforts at the CNRS (the French National Center for Scientific Research) and is protected by 3 patents. The scale up is setting up by the French start-up. As the graphene can be produced in aqueous and organic solvents, it brings key advantages: • Significant effects at very low concentrations. • Fast implementation with no additional capital expenditure (CAPEX). • Compatibility with a wide variety of formulation matrices • Adapted for many industrial processes, such as spray and inkjet, extrusion, injection... The French company has been awarded with several awards at the JEC World show, by the CETIM (the French Technical Center for Mechanical Industry) and the French Ministry of Research and Innovation (I-Lab)
