摘要
摘要 以丙烯酸酯单体和梯形聚硅氧烷（LPSQ）为原料，采用自由基聚合法合成共聚物。采用溶胶-凝胶法制备了不同粒径的纳米二氧化硅溶胶，然后利用逐层自组装法将纳米二氧化硅溶胶涂覆在表面改性的 PET 薄膜上，构建了蛾眼状抗反射涂层。利用红外光谱和 X 射线衍射对 LPSQ 和改性丙烯酸树脂共聚物的结构和组成进行了表征，并使用透射率/霞光测试仪和紫外分光光度计测试了抗反射涂层的性能。热重分析表明，LPSQ 改性共聚物材料的热分解温度高于纯丙烯酸酯共聚物。
Preparation and Study of Moth-Eye-Like Micro-Nano Structure Optical Anti-Reflection Coating
Copolymers were synthesized from acrylate monomers and ladder-shaped polysilsesquioxanes (LPSQ) using free radical polymerization, and the copolymers were coated on polyethylene terephthalate (PET) films by the lift-off impregnation method. The nanosized SiO2 sols with different particle sizes were prepared by sol-gel method, and then the nanosized SiO2 sols were coated on the surface modified PET film to construct a moth-eye-like anti-reflection coating by using the layer-by-layer self-assembly method. The structure and composition of LPSQ and modified acrylic resin copolymer were characterized by infrared spectroscopy and X-ray diffraction, and the transmittance/haze tester and UV spectrophotometer were used to test the performance of the anti-reflection coating, which could reach 94.0% compared with 89.2% of the matrix pure PET film. Thermogravimetric analysis showed that the thermal decomposition temperature of the LPSQ-modified copolymer material was higher than that of the pure acrylate copolymer.
