Description

Technical field [0001] The invention belongs to the field of composite materials, and specifically relates to a graphene epoxy resin composite material. Background technique [0002] Graphene, as a two-dimensional carbon crystal discovered in recent years, has a strength of 130 GPa, making it the strongest material in the world. It also has a large specific surface area, good hydrophobicity and excellent wear resistance. In addition, graphene has better thermal conductivity than any other material at present. Its thermal conductivity is about 4000wm / k, which is 5 times that of copper and 2 times that of diamond. [0003] The composite of graphene and resin matrix can reduce the thermal expansion coefficient of the composite material and greatly increase the thermal conductivity. Adding an appropriate amount of graphene can significantly improve the mechanical properties of the matrix resin and overcome the disadvantages of large amount of general inorganic fillers. Graphene has be...
