▎ 摘 要
NOVELTY - Preparation of graphene porous thin film phase-change energy storage composite material comprises soaking graphene porous film having relative density of 0.1-2 g/cm3 into organic phase change energy storage material until energy storage material entirely fills graphene thin film is pores. USE - Method for preparing graphene porous thin film phase-change energy storage composite material (claimed) used for electronic component. ADVANTAGE - The material has large energy storage density, good thermal conductivity, low cost and light weight.
