Fluorine-containing ternary organic photocatalytic antibacterial coating and preparation method thereof

The invention discloses a fluorine-containing ternary organic photocatalytic antibacterial coating and a preparation method thereof, and belongs to the technical field of photocatalytic antibiosis. The fluorine-containing ternary organic photocatalytic antibacterial coating takes a thienyl polymer heterojunction as an antibacterial component and a fluorine-containing organic material as a carrier, and the mass ratio of the antibacterial component to the carrier is 1: (400-500). The preparation method comprises the following steps: preparing a thienyl polymer dispersion liquid, preparing a proton nano material dispersion liquid, preparing a thiophene nano heterojunction material, preparing the fluorine-containing ternary organic photocatalytic antibacterial coating and the like. The functional polythiophene composite material photocatalytic antibacterial coating prepared by the method is high in biocompatibility, wide in application field, simple in film forming process, convenient to synthesize, efficient and
