▎ 摘　　要

NOVELTY - Preparing graphene oxide/lysozyme antibacterial nanocomposite thin-film material comprises providing a mixed solution of lysozyme and graphene oxide as raw materials to obtain a thin-film material by a solution casting method, where the mass ratio of the lysozyme to the graphene oxide in the mixed solution of lysozyme and graphene oxide is (2-15): 1. USE - The nanocomposite thin-film material is used as an antibacterial material, where the bacteria are Bacillus cereus (all claimed). ADVANTAGE - The nanocomposite thin-film is based on graphene oxide nano-pieces and lysozyme protein and has a highly ordered structure and slow release property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the graphene oxide/lysozyme antibacterial nanocomposite thin-film material obtained by the above method.
