▎ 摘　　要

NOVELTY - Weldable layer containing high thermal conductive graphene thermal control film comprises orderly arranged graphene layer as middle layer structure and weldable layers as upper and lower layers, where the graphene layer is prepared from modified graphene, nano-diamond particles and nano-silicon carbide particles, the modified graphene is obtained from mixed graphene oxide modified by nematic liquid crystal and reduced at high temperature, and the mixed graphene oxide includes graphene powder A having a particle size of 0.01-1 μm and graphene powder B having a particle size of 0.5-3 μm, the weldable layer raw materials include graphene-modified nano-titanium, graphene-modified nano-nickel and graphene-modified nano-cadmium. USE - Used as weldable layer containing high thermal conductive graphene thermal control film. ADVANTAGE - The weldable layer containing high thermal conductive graphene thermal control film can be directly welded with solder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of weldable layer containing high thermal conductive graphene thermal control film, comprising mechanically pressing weldable layer into a target material for magnetron sputtering, and respectively magnetron sputtering the target material onto the upper surface and the lower surface of the graphene layer to obtain final product.
