NOVELTY - Graphene interface material preparation involves mixing 0-20 wt.% graphene, 50-80 wt.% thermally conductive filler, 10-25 wt.% liquid silicone rubber, 0.2-0.5 wt.% hydrogen silicone crosslinking agent, 0.2-0.5 wt.% polymerization inhibitor, 0.1-0.3 wt.% platinum catalyst and 0.5-2 wt.% coupling agent. The obtained mixture is stirred. The obtained stirred mixture is added with toluene. The obtained mixture is heated at 40-100 degrees C. The obtained mixture is stirred for 6-48 hours. The obtained mixture is added with silicone rubber and hexane. USE - Method for preparing graphene interface material (claimed). ADVANTAGE - The method enables to prepare graphene interface material that has high heat conductivity. DETAILED DESCRIPTION - Graphene interface material preparation involves mixing 0-20 wt.% graphene, 50-80 wt.% thermally conductive filler, 10-25 wt.% liquid silicone rubber, 0.2-0.5 wt.% hydrogen silicone crosslinking agent, 0.2-0.5 wt.% polymerization inhibitor, 0.1-0.3 wt.% platinum catalyst and 0.5-2 wt.% coupling agent. The obtained mixture is stirred. The obtained stirred mixture is added with toluene. The obtained mixture is heated at 40-100 degrees C. The obtained mixture is stirred for 6-48 hours. The obtained mixture is added with silicone rubber and hexane. The obtained slurry is stirred. The obtained mixture is dried. The obtained dried mixture is added with coupling agent, polymerization inhibitor, hydrogen silicone crosslinking agent and platinum catalyst. The obtained mixture is stirred, The obtained stirred mixture is molded.
