摘要
采用液相法制备了一系列Co2+掺杂TiO2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TiO2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°。
A series of novel Co^2+/ TiO2 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 Co^2+ 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 Co^2+ content of 1.5% (w,mass fraction),the TiO2 film shows the best hydrophilicity.The contact angle of the film is almost 0.
