采用TiOSO4水性溶胶制备了TiO2薄膜,通过X射线衍射(XRD)、原子力显微镜(AFM)、紫外可见光谱(UV-Vis)和薄膜表面接触角对TiO2薄膜进行了表征并进行了亲水性研究.结果表明采用TiOSO4水性溶胶制备的TiO2薄膜具有优异的光照亲水性;在100-500℃之间热处理,温度的升高有利于亲水性的改善.
TiO2 thin films synthesized from aqueous TiOSO4 solution were characterized by X-ray diffractometry (XRD), atomic force microscopy (AFM) and UV-Vis transmittance measurements. The photoinduced hydrophilicity of the TiO2 thin films was investigated. Results show that the as-synthesized TiO2 thin films have good hydrophilicity; the hydrophilicity can be improved by increasing annealing temperatures at 100-500℃.
