▎ 摘　　要

NOVELTY - A polylactic acid/modified graphene oxide antibacterial plastic comprises polylactic acid-based resin and composite antibacterial agent. The composite antibacterial agent contains graphene oxide on which zinc oxide nanoparticles are loaded. The mass ratio of polylactic acid-based resin and antibacterial agent is 100:0.2-1. USE - Polylactic acid/modified graphene oxide antibacterial plastic (claimed). ADVANTAGE - The environmentally-friendly polylactic acid/modified graphene oxide antibacterial plastic has excellent reliability and odorless, and is harmless with respect to human body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polylactic acid/modified graphene oxide antibacterial plastic, which involves mixing chloroform, polylactic acid and composite antibacterial agent, coating on the surface of clean glass, naturally cooling, evaporating, and drying.
