Abstract

The invention provides a preparation method of a glass fiber titanium-dioxide-loaded composite material. According to the method, an organic or inorganic titanium compound is used as a titanium source and a glass fiber is used as a carrier to prepare a glass fiber titanium-dioxide-loaded nano grain composite material under an acidic condition through using a direct hydrolysis method; the shape controllability of glass fiber titanium-dioxide-loaded nano grains is realized by adjusting parameters of acid concentration, reaction time and the like of a reaction system. According to the method provided by the invention, the surface modification of the glass fiber is realized by using a one-step method; meanwhile, titanium dioxide with photocatalytic activity is uniformly loaded on the surface glass fiber; the method has the advantages of simplicity and convenience for operation, easiness of large-scale production and the like. The composite material has the characteristics of nano / micron multilayered-grade structure, large specific surface area, high catalytic performance and the like, and lays a foundation for the application to the fields of photocatalysis, antibiosis, phase-separation materials and the like.
