溶胶–凝胶法制备PHFBMA/PFG/SiO 2 短波长持效增透膜
Source abstract
Abstract
在碱性催化条件下, 以正硅酸乙酯为前驱体，制备了一种新的、光谱性能持效的短波长减反膜。溶胶制备中，采用20氟基－1, 12－十二醇（PFG）控制了二氧化硅颗粒的结构和尺寸，从而一定程度地减小了薄膜的折射率。以PFG修饰的二氧化硅为基础，再采用甲基丙烯酸六氟丁酯的聚合物(PHFBMA)对溶胶进行改性，得到了适用于熔石英基底的PHFBMA/PFG/SiO 2 减反膜。该改性减反膜在300 nm左右可以达到99.9%的透过率，并且一定湿度条件下和含有机污染物的真空腔室内的考察结果表明，该改性膜层的透过率稳定性获得了显著提升。
