Development of the low-temperature sol-gel synthesis of TiO_2 to provide self-cleaning effect on the textile materials

摘要

This work is devoted to the development of "smart textiles" possessing high photocatalytic activity in the decomposition of organic compounds. To modify cotton fibers, the nanocrystalline TiO_2 sol was used. 1,2,3,4-Butane tetracarboxylic acid was used as a spacer. Photoactive nanoparticles were formed as a result of low-temperature sol-gel synthesis, leading to the formation of titanium dioxide of anatase-brookite modification. The self-cleaning properties of the modified textile materials were estimated by the decomposition of Rhodamine B under UV irradiation.
