Graphene and its application in polymer composites

This paper looks at the development of graphene/pol ymer nanocomposites to be used as adhesives for Thermal Interface Materials (TIMs) an d lightweight high performance CFRP composite laminates with conductive properties. The addition of graphene, even at a very low concentration level (usually less than 5%), into a polymeric matrix can significantly improve its thermal conductivity. The achievement of a good dispersion of graphene and the interfacial bonding of graphene and the polymer mat rix is a key aspect. Different qualities of graphene material have been characterised and teste d to obtain good dispersion in the polymer matrixes tested. High improvements in the thermal conductivity for b th applications under study have been achieved.
