NOVELTY - High thermal conductivity carbon fiber composite material comprises self-supporting three-dimensional network of oriented interconnected carbon fiber and polymer matrix constructed by using graphene oxide as bridging agent. USE - High thermal conductivity carbon fiber composite material. ADVANTAGE - The high-oriented carbon fiber self-supporting structure prepared by using graphene oxide as a bridging agent, without the wrapping of traditional polymer binder, and the carbon fiber is effectively connected to each other through graphene oxide, and together they form a synergistically oriented three-dimensional thermally conductive enhanced network structure, which significantly improves the thermal conductivity of the composite material at a low filling amount. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a high thermal conductivity carbon fiber composite material, which involves: (a)dispersing uniformly carbon fiber in a graphene oxide aqueous solution;(b)using graphene oxide as a bridging agent;(c)using the self-assembly characteristic of the graphene oxide;(d)forming self-supporting three-dimensional carbon fiber framework by interconnection and directional arrangement of carbon fiber;(e)preparing graphene oxide by an ice template method or a hydrothermal reduction assembly combined vacuum drying process;(f)compounding the polymer matrix and curing to obtain the corresponding polymer composite material with high heat conductivity, where the heat conductivity coefficient is 4.3-17.6 watts per meter/Kelvin. DESCRIPTION OF DRAWING(S) - The drawing shows a surface scanning electron microscope image of the prepared three-dimensional carbon fiber skeleton along the height direction.
