摘要
采用溶胶-凝胶法在普通载波片上制备了TiO2薄膜,用AFM、XRD、UV-VIS分光光度计、润湿角测量仪研究了薄膜的表面形貌和热处理温度对薄膜各种性能的影响.结果表明:TiO2薄膜由大量的球形纳米颗粒构成,颗粒大小均匀;随着热处理温度的升高,TiO2薄膜晶粒尺寸不断长大,亲水性和光催化性能提高;600℃时部分TiO2由锐钛矿转变为金红石相,使紫外光吸收线“红移”.
TiO2 thin films were prepared on slide glass substrates by sol-gel method. Surface microstructure and the influences of heating temperatures on verious properties of TiO2 thin films were investigated by AFM, XRD,UV-VIS spectrophotometer, Wetting angle goniometer. The results indicate that TiO2 thin films are composed of spherical nanoparticles with mono-disperse size ; crystal size, hydrophilicity and photocatalytic of TiO2 thin films are improving with heating temperature increasing. Crystal of partial TiO2 changed from anatase to rutile in 600 ℃, which induced absorb edge of UV moved towards the visible light.
