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