▎ 摘　　要

NOVELTY - Metal-organic framework in-situ modified graphene/polymer composite material comprises polymer and metal-organic framework dispersed in polymer in-situ modified graphene nano-filler. The metal-organic framework in-situ modified graphene nanofiller of framework is obtained by in-situ growth of metal-organic framework on graphene nanosheet structure. USE - Metal-organic framework in-situ modified graphene/polymer composite material used for preparing film capacitors (claimed). ADVANTAGE - The metal-organic framework in-situ modified graphene/polymer composite material combines advantages of both conductive filler and polymer matrix, obtains large dielectric constant at low filling amount, and has good energy storage density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing metal organic framework in situ modified graphene/polymer composite material, which involves: a. dissolving polymer in organic solvent, heating and stirring, adding metal-organic framework in-situ modified graphene nanofiller, and continuing to heat and stir to prepare casting solution, where heating temperature is 60-80degreesC; b. drying film casting solution to prepare metal organic framework in-situ modified graphene/polymer composite material.
