TiO2 thin films were prepared by vacuum deposition on the glass substrates and annealed at 300℃,400℃,500℃ and 600℃ respectively.The influences of deposition time,annealing temperature and annealing time on hydrophilicity of the TiO2 thin films were studied by using UV-vis abosorption spectrum,X-ray diffraction,scanning electron microscopy and contact angle measurement the aim was to find the optimum technology of preparing hydrophilic TiO2 thin films by vacuum deposition.The results reveal that TiO2 thin fi...

0引言自1972年Fu jish im a Ak ira和Honda Katsuh isa[1]在TiO2表面发现了光诱导分解水的反应以来,TiO2作为一种无污染、清洁高效的催化剂,在过去30年受到了很大的关注。1997年,R.W ang[2]发现在紫外光照射一段时间后,水在TiO2薄膜上的接触角变为了0°,即TiO2薄膜的光诱导超亲
