▎ 摘　　要

NOVELTY - Preparing antibacterial fabric by layer-by-layer self-assembly comprises (i) soaking cotton fabric in chitosan finishing liquid to obtain cotton fabric having positive electricity on the surface, (ii) taking modified graphene oxide solution as polyanion solution, chitosan acidic solution as polycation solution, soaking the cotton fabric having positive electricity on the surface in the modified graphene oxide solution, and then soaking in the chitosan acidic solution to finish layer-by-layer self-assembly of first layer, and repeating the assembling process to obtain antibacterial fabric, where the modified graphene oxide is halogenated amine modified graphene oxide. USE - The method is useful for preparing antibacterial fabric by layer-by-layer self-assembly. ADVANTAGE - The method has mild reaction condition and simple technique. The fabric has excellent antibacterial performance and excellent service performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for antibacterial fabric prepared by above method.
