▎ 摘　　要

NOVELTY - Directionally arranged graphene/epoxy resin composite material with high thermal conductivity comprises thickness of 5-20 mu m, graphene soaking film pieces with lateral size of 0.5-3 mm as thermally conductive fillers, cured at high temperature together with the epoxy resin poured and coated with the thermal conductive material, and the graphene soaking film pieces to complete the final orientation arrangement. USE - Used as directionally arranged graphene/epoxy resin composite material with high thermal conductivity. ADVANTAGE - The graphene soaking film realizes waste utilization. The composite material has good thermal conductivity due to the highly oriented filler. The method is simple mechanical extrusion or airflow positive pressure, has simple steps, and easy realization of industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing directionally arranged/epoxy resin composite material with high thermal conductivity, comprising (i) pre-setting high-temperature curing forming mold device, the device comprises mold comprising bottom plate, (ii) adding the leftovers of the graphene soaking film with set quality into mechanical pulverizer, sieving the fragments of the graphene soaking film for screening graphene with thickness of 5-20 um and lateral dimension of 0.5-3 mm, and using as thermally conductive fillers as soaking film pieces, (iii) loading the graphene soaking film fragments and thermally conductive fillers into mold device one by one, arranging graphene fragments loaded each time inside the mold along the direction parallel to the bottom plate of the mold, repeating loading and directional arrangement many times, until all graphene soaking film piece is added into the mold, and completing directional arrangement, (iv) pouring epoxy resin into the mold, vacuum degassing for 3-5 times, discharging the air in the graphene soaking film pieces, and (vi) placing the epoxy resin pouring mold into the oven for high temperature curing, completing curing, and releasing the mold to obtain product.
