▎ 摘　　要

NOVELTY - Production of reduced graphene-gel composite involves performing reduction of graphene oxide and polymerizing a dopamine-based monomer by irradiating radiation on mixed solution of graphene oxide and dopamine-based monomer. USE - Production of reduced graphene-gel composite used for semiconductor filler, and shielding human radiation (all claimed). ADVANTAGE - The method is environmentally-friendly, and enables production of reduced graphene-gel composite having excellent dispersibility in an aqueous solution state. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the reduced graphene-gel composite, which comprises reduced graphene oxide, and dopamine-based polymer chemically bonded to the reduced graphene oxide.
