采用液相法制备了一系列 Co2+掺杂 TiO 2纳米复合薄膜,利用 X 射线粉末衍射(XRD)、扫描电镜(SEM)、紫外-可见(UV-Vis)光谱、可见光透过光谱等手段对复合薄膜进行了表征,运用接触角测量仪考察了各薄膜的亲水性能。结果表明,Co2+的掺杂大幅度提高了 TiO 2薄膜的亲水性,当掺杂 Co2+的质量分数为1.5%时,薄膜与水的接触角几乎为0°。
採用液相法製備瞭一繫列 Co2+摻雜 TiO 2納米複閤薄膜,利用 X 射線粉末衍射(XRD)、掃描電鏡(SEM)、紫外-可見(UV-Vis)光譜、可見光透過光譜等手段對複閤薄膜進行瞭錶徵,運用接觸角測量儀攷察瞭各薄膜的親水性能。結果錶明,Co2+的摻雜大幅度提高瞭 TiO 2薄膜的親水性,噹摻雜 Co2+的質量分數為1.5%時,薄膜與水的接觸角幾乎為0°。

A series of novel Co2+/ TiO 2 Nano-films were synthesized by a liquid phase method.The as-synthesized products were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),UV-Vis diffuse reflec-tance spectroscopy (DRS),visible light spectrum.Influence of doping Co2+ content,saving time in dark place and UV illumination time on the hydrophilicity of the film were investigated by contact goniometer.The results indicate that doping Co2+ content of 1.5% (w,mass fraction),the TiO 2 film shows the best hydrophilicity.The contact angle of the film is almost 0.
