The graphene material market, bulk graphene, graphene nanoplatelets and graphene films, will grow to 350 € million in 2025. Their application in composites is the largest segment, followed by energy storage . Several reviews analysed the applications of the different graphene and related products in in composites.[2, 1b]. Currently, a variety of techniques have been developed to prepare graphene materials. In this presentation, 3 different methods for the production of bulk graphene or reduce graphene oxide: liquid exfoliation, reduced graphene oxides and high expansion were compared with other carbon materials. The complete characterization of pristine graphene and highly reduce graphene oxide, will be presented.
Different types of graphene materials with variation in lateral size, defects and defects concentration, thickness, etc, have been used to obtain graphene-thermoplastic and thermoset composites studying the electrical, thermal conductivity and fire retardant properties of the composites. Related to electrical properties, some of these composites show ultralow percolation threshold limits, lower than the previously reported values, also obtaining very high electrical conductivity, opening a new range of applications and markets. We have also obtained high thermal conductive composites align with the best published result for graphene composites. Other factors as processing technique have been analysed due to their extremely high importance in the final results.

Julio Gomez is the Founder of AVANZARE, company producer of graphene and other 2D materials and its composites . He is primarily interested in the mechanical properties of atomically thin materials such as graphene. He received his B.S. degree in Chemistry from Universidad Complutense de Madrid (1995), receiving the and a Ph.D. in Chemistry (2000) from University of La Rioja where he studied the preparation and electrical and optical properties of nanosize metallic clusters, and a postdoctoral researcher position in the Laboratoire de Synthèse Organique, University of Nantes-CNRS After finishing his Ph.D, he spent 3 years as assistant Professor in Universidad de La Rioja and 2 years as an Area Manager in the research centre CIDETEC studying electrochemical systems before joining AVANZARE at the end of 2004. His awards include among others the best B.S. degree in Chemistry in 1995 award in the University Complutense de Madrid, the best PhD degree in Science and Technology award in the University of La Rioja from the years 1999-2000, National award Entrepreneur of the year 2008 in Spain, best product NANOAWARDS 2008 (USA), F&S best practices in innovation 2013 (UK).
