| 摘 要： | 采用反应溅射技术可以制备出具有亲水作用的TiO2薄膜。这种TiO2薄膜断面呈现柱状晶体结构。薄膜表面出现不规则起伏。薄膜的晶相主体均为锐钛矿型。TiO2薄膜的光透射谱变化不大。这种TiO2薄膜经紫外光辐照后,可以降低水和TiO2薄膜表面之间的接触角。不同工艺条件下制备的TiO2薄膜接触角相差很大。在纯氧条件下,薄膜制备的真空度对薄膜的亲水性有着决定性的影响。

| Abstract: | Titanium oxide films were grown by reactive magnetron sputtering under different pressures of pure oxygen,ranging from 1.0 Pa to 4.0 Pa,at a fixed oxygen flow rate of 10 cm3/min.The surface microstructures were characterized with X-ray diffraction(XRD) and atomic force microscopy(AFM).The results show that the film gorwn under the oxygen pressure of 2.5 Pa displays the best hydrophilicity.Interesting finding is that ultraviolet light irradiation considerably reduces its water contact angle.Possible mechanism(s) was also tentatively discussed. |
