Preparation method of photocatalytic antibacterial viscose spunlaced non-woven material

The invention discloses a preparation method of a photocatalytic antibacterial viscose spunlaced non-woven material, which comprises the following steps: step 1, preparing a nano TiO2 suspension, and carrying out nano TiO2 finishing on the viscose spunlaced non-woven material; step 2, preparing Se nanowires by adopting a hydrothermal method; and step 3, loading the Se nanowires on the nano-TiO2 through a molecular assembly method to generate a viscose/TiO2/Se composite structure. The raw materials are green and pollution-free and have biocompatibility and degradability, the Se-coated TiO2 composite structure is generated on the surface of the viscose spunlace non-woven material, the material is endowed with excellent visible light photocatalytic performance and antibacterial function, and the bacteriostasis rate on escherichia coli and the bacteriostasis rate on staphylococcus aureus reach 95% and 99%. 本发明公开了一种光催化抗菌粘胶水刺非织造材料的制备方法，包括如下步骤：步骤一、制备纳米TiO2悬浮液，将粘胶水刺非织造材料进行纳米TiO2整理；步骤二、采用水热法制备Se纳米线；步骤三、通过分子组装法将Se纳米线负载
