Abstract:

In order to solve the problems of unstable crystal structure, long photochromic response time and short life of tungsten oxide, light yellow tungsten oxide nanorods were prepared by the hydrothermal one-step method for uniform dispersion into polyvinyl alcohol solution with aid of magnetic stirring. Cotton fiber was coated with tungsten oxide nanorods by rapid and continuous impregnation coating process, and its structure and properties were characterized. The results show that under the irradiation of ultraviolet light, the color of photochromic fiber changes from light yellow to grayish blue in 1 min, and gradually to dark blue in 5 min, and the color of photochromic fiber returns to its initial state in about 2 h during infrared heating treatment, showing a fast and reversible color switch from light yellow to dark blue. The photochromic fiber can be produced on a large scale and can be woven into various patterns, which has great potential in developing photochromic textiles.

Key words: photochromic fiber, tungsten oxide nanorod, hydrothermal one-step method, solution coating method, smart clothing
