摘要/Abstract

摘要： 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。

关键词: ZrO₂, TiO₂, PVDF, 光学膜

Abstract: To improve the integrative properties of ZrO₂-TiO₂ optical film, polyvinylidene fluoride (PVDF)/ZrO₂-TiO₂ film was coated on the K9 glass substrate by Sol-Gel method using ZrOCl₂·8H₂O and Ti(OBu)₄ as precursor of Zr and Ti, respectively. Using PVDF as organic additive, PVDF/ZrO₂-TiO₂ optical films were characterized by SEM, FT-IR and contact angle. Then the optical properties of the PVDF/ZrO₂-TiO₂ optical films were investigated via Ultraviolet/ Visible/Near Infrared transmission spectrum, optical band gap (E_g) and refractive index. SEM images indicate that the optical films are successfully prepared on the glass substrates. The addition of PVDF in the optical films increases the contact angle between water and the films. E_g of ZrO₂-TiO₂ optical films are slightly widened with the increasing of ZrO₂ content, and E_g of PVDF/ZrO₂(50mol%)-TiO₂films are widened as the mass fraction of PVDF increases. In addition, refractive indexes of ZrO₂-TiO₂optical films increase as the mole fraction of ZrO₂ decreases, and refractive indexes of PVDF/ZrO₂(50mol%)-TiO₂ films increase as the mass fraction of PVDF increases.
