Hybrid silica sol photocatalytic antibacterial coating and preparation method thereof

The invention discloses a hybrid silica sol photocatalytic antibacterial coating and a preparation method thereof, and belongs to the technical field of photocatalytic antibiosis. According to the photocatalytic antibacterial coating, a thienyl polymer serves as an active component, inorganic hybrid sol serves as a carrier, and the thienyl polymer is PD-(COOH) 2 or PD-COOH and has no fixed morphology; the carrier is inorganic hybrid silica sol or inorganic hybrid silicon-titanium sol. The preparation method comprises the following steps: preparing a polymer, preparing hybrid sol, forming a bond between the polymer and the hybrid silica sol by adopting a thermal polymerization method to prepare the antibacterial sol coating, and the like. The polythiophene hybrid silica sol photocatalytic antibacterial coating is high in biocompatibility, wide in application field, simple in film forming process, convenient to synthesize, efficient and stable. 本发明的一种杂化硅溶胶光催化抗菌涂层及其制备方法属于光催化抗菌技术领域。所述光催化抗菌涂层，以噻吩基聚合物作为活性组分，无机杂化溶胶作
