【Abstract】 TiO 2 liquid was prepared by sol gel and its film was made in optical fiber by dip coating. The phase of the film was only sized by X ray diffract meter and the results showed that it was sharp TiO 2 anatase phase. The results of erosion experiments and measure of adhesion in dictated that the film showed excellent erosion resistance and adhesion. Simultaneously, the photo catalytic oxidation mechanism of the film was theoretically studied, and the results indicated that it was feasible and superior in treatment of the pulled water. The development and improvement of synthesizing the film were discussed.更多还原
