Abstract

The ever-growing demand of society for efficient miniature devices for sustainable applications has driven the search for novel products, materials and innovative solutions. Conductive inks and adhesives respond to this demand, constituting a global market of around US$20 billion, with a CAGR valued at 5-10%, over the next few years. Currently, the product that dominates the market is silver due to its high conductivity, but there are great expectations that advanced materials based on non-metallic conductive compounds such as graphenes and nanographites will lead the market in the future. This project explores a new non-metallic and multifunctional conductor that is exfoliated and reassembled graphite (ERG), produced by exfoliating graphite in aqueous cellulose solutions. The coatings resulting from their application on surfaces form a new class of products inserted in the paradigms of circular economy and green chemistry. The process used is scalable, carried out under mild conditions of temperature and pressure, therefore with low energy impact, uses low-cost, available raw materials, requires simple equipment and generates very little waste. The use of ERG inks in different applications has already allowed the creation of new technological products in different TRLs, from the laboratory to commercialization. Some applications are: low cost, flexible and efficient electrodes, sensors, power generators and heaters, flame retardant and antistatic coatings. The current objective is the development, optimization and industrial production of ERG paints, coatings, and their applications, raising the level of maturity of the technologies on this platform to the upper stage.
