摘    要:
以正硅酸乙酯(TEOS)和钛酸正丁酯(TBOT)为原料,采用溶胶-凝胶法制备了SiO2溶胶和TiO2溶胶,利用浸渍提拉法制备了SiO2/TiO2双层减反膜.用紫外-可见分光光度计(UV-Vis)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)、原子力显微镜(AFM)、椭圆偏振光谱仪和接触角测量仪等分析表征了薄膜的特性,以光催化降解甲基橙溶液实验来评价薄膜的自洁功能,考察了SiO2/TiO2双层减反膜的耐磨擦性.结果表明,SiO2/TiO2双层减反膜在400~800nm可见光波段的透光率最高可达97.2%,薄膜表面平整,结构致密且粗糙度小,经紫外灯照射后薄膜的水接触角接近0°,光催化2h后可将5mg/L的甲基橙溶液降解43.6%.SiO2/TiO2减反膜还具有优良的耐磨擦性能.

关 键 词:溶胶-凝胶  减反膜  自洁功能  耐磨擦性

Abstract:
The SiO2 and TiO2 Sol were prepared via Sol-Gel process using tetraethyl orthosilicate(TEOS) and tetrabutyl orthotitanate(TBOT),and the SiO2/TiO2 bilayer coatings with antireflection property were obtained by dip-coating method.The performances of the coatings were analyzed with ultraviolet visible spectrophotometer(UV-Vis),X-ray diffraction(XRD),scanning electron microscope(SEM),atomic force microscope(AFM),ellip-someter and contact angle measurement.The self-cleaning function of coatings was evaluated by ...
Keywords:Sol-Gel  antireflective coatings  self-cleaning  scratch-resistant
