Abstract

The invention discloses a method for preparing a titanium dioxide nanorod / polypyrrole / dacron compound fabric. The method comprises the steps of cleaning and drying a dacron fabric, and then placing the dacron fabric in alkali aqueous ammonia for surface roughness treatment; then soaking the dacron fabric in an oxidization bath, and adding pyrrole monomer aqueous solution dropwise so that a polypyrrole layer can be deposited on the surface of the dacron fabric; soaking the dacron fabric with polypyrrole deposited on the surface in prepared titanium dioxide sol, conducting lifting, drying and hydrochloric acid treatment so that a titanium dioxide seed crystal layer can be deposited on the surface of the dacron fabric, and conducting hydrochloric acid treatment and sulfuric acid treatment in sequence; preparing titanium dioxide nanorod growth-promoting media, and adding an excessive amount of titanium source so that titanium dioxide nanorods can be deposited and grown on the surface of the treated dacron fabric. Combination of the one-dimensional titanium dioxide nanorods and polypyrrole on a substrate of a flexible fabric is realized, and the obtained compound fabric has self-cleaning, anti-statistic, photocatalytic degradation and pollutant filtration functions and can be used as a flexible electrode and a flexible supercapacitor.

Description

technical field [0001] The invention relates to a preparation method of a titanium dioxide nanorod / polypyrrole / polyester composite fabric, belonging to the technical field of energy and environmental materials. Background technique [0002] Titanium dioxide (TiO 2 ), compared to ZnO, Fe 2 o 3 , ZnS, CdS and other semiconductor photocatalysts have higher chemical stability, and excellent biocompatibility, non-toxic and harmless. , sterilization, solar cells, self-cleaning, gas sensors and humidity sensors and other aspects of the performance of the eye-catching, has important application prospects. But TiO 2 It can only absorb ultraviolet light and has low utilization rate of solar energy. Zero-dimensional TiO 2 Although nanoparticles have high photocatalytic activity, they are difficult to recycle and easily cause secondary pollution of water bodies. Therefore, the preparation of 1D TiO with high photocatalytic activity 2 Nanostructured thin films are particularly im...
