Study on preparation and hydrophilicity of N and Fe3+ co-doped TiO2 film

摘要: 采用溶胶-凝胶法制备了N和Fe3+共掺杂的TiO2薄膜,研究了N,Fe3+不同掺杂比例、镀膜层数、热处理温度和光照时间等对TiO2薄膜亲水性能的影响.结果表明当掺杂物N和Fe3+的摩尔比为5.9:1、镀膜层数为3层、热处理温度为550℃时,所制备的薄膜亲水性能最佳(接触角为2°).

Abstract: N and Fe3+ co-doped TiO2 thin film were prepared by Sel-gel process.The influences of different N and Fe3+ ratio,film thickness,heat-treated temperature and sunlight irradiating time on the film hydrophilicity were studied.The result indicated that the hydrophilicity is the best(contact angle is 2°) as the mol ratio of N and Fe3+ is 5.9:1,the thickness is 3 cycle coating and the heat-treated temperature is 550 ℃.
