▎ 摘 要
NOVELTY - A polymer-graphene composite comprises graphene and a polymer bonded to the graphene through a functional group containing a carbonyl group and 1-20C alkylene group. USE - Polymer-graphene composite is used for forming composition (claimed). Uses include but are not limited to secondary battery, solar cell, display material, and electronic material. ADVANTAGE - The polymer-graphene composite has excellent mechanical property and dispersibility with respect to organic solvent. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of polymer-graphene composite, which involves reacting halogenated compound containing the functional group and two or more halogen elements with graphene, and reacting resultant product with polymerizable monomer; and (2) polymer-graphene composite composition, which contains the polymer-graphene composite dispersed in a binder resin or a solvent.
