▎ 摘　　要

NOVELTY - Grafted graphene heat dissipation silicone composition comprises 30-60 wt.% silicone rubber, 5-15 wt.% grafted graphene powder, 1-5 wt.% modified carbon nanotube powder, 0.3-3 wt.% crosslinking catalyst, 3-10 wt.% curing agent, 10-50 wt.% solvents and 0.1-2 wt.% adhesives. USE - The grafted graphene radiating silica gel is useful in interface radiating material (claimed). ADVANTAGE - The graphene filler particles in the grafted graphene radiating silica gel composition is modified by grafting, which not only can keep the structure of graphene, but also has better dispersibility in the silicon rubber matrix; it is not easy to accumulate to enhance the forming of the heat conducting path, increases the radiating performance of the composite interface material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for (1) preparing grafted graphene heat-dissipating silica gel using the grafted graphene heat-dissipating silica gel composition comprising mixing grafted graphene powder, the modified carbon nanoparticle, tube powder, the solvent, the silicone rubber, the curing agent and the adhesive stirring, and introducing cross-linking catalyst for curing. (2) grafted graphene heat-dissipating silica gel prepared by method.
