以氧氯化锆(ZrOCl2.8H2O)为锆源,钛酸丁酯(Ti(OBu)4)为钛源,聚偏氟乙烯(PVDF)为有机添加剂,采用溶胶-凝胶法在K9玻璃基片上制备PVDF/TiO2-ZrO2光学膜,提高了ZrO2-TiO2光学膜的综合性能.然后采用SEM、FT-IR、接触角以及紫外/可见/近红外透射光谱等手段对PVDF/TiO2-ZrO2光学膜的组成、光学性能和抗激光损伤阈值进行了研究.SEM测试表明,在K9玻璃基片上制备了光学膜.PVDF的添加导致水与薄膜的接触角增大.ZrO2-TiO2光学膜的光学带隙随ZrO2含量的增加而略微增大,PVDF/ZrO2(50mol％)-TiO2薄膜的光学带隙随PVDF质量分数的增加而增大.另外,ZrO2-TiO2光学膜的折射率随ZrO2摩尔分数的减小而增大,PVDF/ZrO2(50mol％)-TiO2膜的折射率随PVDF质量分数的增加而增大.
