Abstract

Abstract Nano-TiO2 film attracts great attention by its excellent photocatalytic activity performance. The application of nano-TiO2 film based on fabric substrate in indoor household textiles is helpful for purifying air and degrading formaldehyde content in indoor environments. In this paper, the nano-TiO2 films were prepared on fiberglass substrate by the sol-gel method, and the appearance of fabrics coated with nano-TiO2 at conditions of both without calcination (room temperature) and high temperature calcination (300C, 350C, 400C) was studied. In addition, X-ray diffraction technology was applied to analyze the crystallization of TiO2 film, with further discussion of the photocatalytic performance of degrading helianthin under UV irradiation.The results show that with increase of calcination temperature, the color of the fabric gets darker and darker until the powder peeling and dyeing reaches the maximum degree, the fabric becomes fragile, the anatase crystal form of TiO2 film tends to be complete, and the photocatalytic performance is improved. It is feasible to apply TiO2 film on the surface of fabrics in the design of indoor household textiles.
