▎ 摘　　要

NOVELTY - A multifunctional air-purifying film comprises a multifunctional layer supported on a nonwoven fabric as a base film, alternately formed by spraying a mixture comprising organic polymer material, nano-grained graphene oxide and fluorescent conjugated polymer in mass ratio of 50-300:3-6:1. The loading amount of multifunctional layer on the base film is 0.8-10 g. The multifunctional layer is a mixture of nano-grained graphene oxide and fluorescent conjugated polymer in mass ratio of 5-20:1. The pore size of the film is 0.2-12 mu m. The thickness of the film is 500-5000 mu m. USE - Multifunctional air-purifying film (claimed). ADVANTAGE - The multifunctional air-purifying film has excellent antibacterial effect and durability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of multifunctional air-purifying film; and (2) fluorescent conjugated polymer, which is poly-3-(1,4-dioxa-6-bromo-trimethylamino-hexyl)thiophene-co-3-(1,4,7-trioxa-octyl)thiophene of formula (I). m1,m2=1-10.
