为了提高镀膜玻璃的可见光透过率,本研究通过反胶束溶液刻蚀法制备出一种新型玻璃基板,即表面多孔玻璃.玻璃表面形成了蜂窝状的多孔膜层,减小了对可见光的反射率,从而使可见光平均透过率提高了7%.通过一系列射频磁控溅射实验,探索了可见光平均透过率高,紫外阻隔率最高的最佳工艺条件.在此条件下,分别在制备的表面多孔玻璃和普通玻璃上镀CeO2/TiO2防紫外线膜,并采用紫外–可见分光光度计、SEM、XRD、XPS等测试手段对样品进行了分析表征.结果表明,在相同的镀膜条件下,当镀膜后表面多孔玻璃与镀膜普通玻璃的紫外光阻隔率均为99%时,表面多孔玻璃镀膜后的可见光平均透过率为85%,而普通玻璃镀膜后的可见光平均透过率仅为79%.此外,玻璃表面上的孔结构还提高了薄膜与基板的接触面积,使膜基结合力提高2倍左右.%A glass with a honeycomb surface was prepared by a reverse micellar solution etching technology. The honeycomb surface might reduce the light reflection and increase the average transmittance of visible light by nearly 7%. The chemical etching technology is environment friendly for unuse of HF or fluosilicate. To compare the visible light transmittance of the coated glass, CeO2/TiO2 films were deposited on the honeycomb surface glass and raw glass by radio frequency magnetron sputtering. A series of optimization experiments were carried out to obtain a coated glass with high visible transmittance and high UV cut-off. The samples were characterized by UV-Vis spectropho-tometer, SEM, XRD, and XPS. When the UV cut-off ratios were 99% for both the honeycomb surface glass and the raw glass, the average transmittance of visible light was 85% for the coated honeycomb surface glass, and only 79%for the coated raw glass prepared under the same coating conditions. In addition, the porous structure on the glass sur-face also improved the contact area between the film and the substrate. Therefore, the binding force between film and substrate was increased by about 2 times.
