| Abstract: | The polymeric gel method was applied for the preparation of TiO 2 gelatin.The preparation process was investigated under different conditions (such as the amount of water,acid and solvent added,different kinds of solvent,the temperature and the atmospheric conditions) with Ti(OBu) 4 as the chelator and HAc as a precursor.The optimum conditions were obtained,and the mechanism of sol gel process was discussed. |
