▎ 摘　　要

NOVELTY - Medicine packaging film comprises a polymer film and a graphene coating coated onto the polymer film. The graphene coating comprises graphene and a photocurable adhesive. The photocurable adhesive comprises a hyperbranched cationic imitation mussel polymer. The hyperbranched cationic imitation mussel polymer comprises a poly-o-phenolic hydroxybenzophenone amide monomer, a cationic monomer, and a photoresponsive monomer. USE - Used as medicine packaging film. ADVANTAGE - The method is simplified. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing medicine packaging film, comprising (a) preparing hyperbranched cationic imitation mussel polymer by reversible addition-fragmentation chain transfer polymerization and further configuring the prepared hyperbranched cationic imitation mussel polymer as an aqueous binder solution, (b) preparing a reduced graphene oxide solution, (c) adding the aqueous solution of the binder prepared in the step (a) to the reduced graphene oxide solution prepared in the step (b), stirring uniformly to obtain a graphene coating solution, and (d) coating the graphene coating solution to the polymer film and drying to form a graphene coating.
