▎ 摘　　要

NOVELTY - A functionalized graphene oxide (I), is new. The solvent dispersibility of functionalized graphene oxide is regulated and controlled by organic chain segment. USE - New functionalized graphene oxide is used for preparing nanoparticles/polymer nano composite material. ADVANTAGE - The functionalized graphene oxide has excellent dispersibility with respect to organic solvent having reduced polarity and boiling point, and compatibility with various polymer molecules. DETAILED DESCRIPTION - A functionalized graphene oxide of formula (I), is new. The solvent dispersibility of functionalized graphene oxide is regulated and controlled by organic chain segment. R=group chosen from groups of formulae (i-iii). An INDEPENDENT CLAIM is included for preparation of functionalized graphene oxide.
