▎ 摘 要
NOVELTY - A polymer-functionalized graphene comprises graphene that is connected with a polymer through imide, amide, ester and amine groups. The polymer has molecular weight of 200000-500000 containing benzene ring that interacts with graphene via a covalent bond and/or hydrogen bond. USE - Polymer-functionalized graphene used in multifunctional additive of lubricating oil composition and plastic, rubber, coating or adhesive composition (all claimed). ADVANTAGE - The polymer-functionalized graphene has improved dispersibility, storage stability and non polar solvent resistance.
