TiO₂-SiO₂Nanocomposite Fibers Prepared by Electrospinning of Ti-PCS Mixed Solution

Abstract

Nanostructured TiO 2 -SiO 2 materials have widely been used as anti-reflecting coating, optical-chemical sensors and catalysts because of their superior optical and thermal properties as well as chemical durability. Web type SiO 2 microfibers with nano-crystalline TiO 2 were prepared by electrospinning of Ti-PCS mixed solution and oxidation controlled heat-treatment, rather simple than sol-gel process. Nano-crystalline anatase phase were formed for the heattreatment up to 1200°C and they were finely dispersed in the amorphous SiO 2 matrix.
