▎ 摘　　要

NOVELTY - A polyacrylonitrile/graphene oxide/tea polyphenol composite based antibacterial air filtration film is prepared by utilizing non-woven fabric as a substrate, and depositing surface of the substrate with polyacrylonitrile/graphene oxide/tea polyphenol complex, at mass ratio of (16-30): (4-10):(1-16). USE - Polyacrylonitrile/graphene oxide/tea polyphenol composite based antibacterial air filtration film. ADVANTAGE - The filtration film improves the filtration efficiency, effectively maintains the pressure drop of the film, has improved effect of filtering PM2.5 in the air, and better antibacterial properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing polyacrylonitrile/graphene oxide/tea polyphenol composite based antibacterial air filtration film.
