用不同陈化时间的碱性催化的溶胶，经提拉法镀膜，得到不同增透效果的光学膜层。分析发现，随着与陈化时间相关的水解和聚合反应的进程，溶胶的粒度分布发生变化，形成不同粒径的“簇团（Ｃｌｕｓｔｅｒｓ）”，拉膜后，形成不同的孔径分布，由此影响光学透过率特性。本文给出了与最佳增透效果相对应的溶胶粒度分布范围。
Alkaline catalyzed sols with different aging times were coated by the pulling method to obtain optical coatings with different antireflection effects. It was found that the particle size distribution of the sol changed with the progress of hydrolysis and polymerization reaction related to the aging time to form “Clusters” with different particle sizes, and different pore size distributions were formed after drawing the film, Affect the optical transmittance characteristics. This article gives the range of sol particle size distribution corresponding to the best AR effect.
