摘要：以巯丙基三甲氧基硅烷（MPTMS）和 3-(甲基丙烯酰氧)丙基三甲氧基硅烷为（MATMS）为原料，经巯-
烯点击反应制备有机桥连硅烷前驱体 3-三甲氧硅基丙基-2-甲基-3-[(3-三甲氧硅基)丙基硫代]丙酸酯（MPMA）。
采用溶胶-凝胶法，MPMA 在酸性条件下水解-缩聚得到溶胶，将其分别沉积在载玻片和聚醚酰亚胺（PEI）上得
到有机桥连聚倍半硅氧烷涂层。通过测试水蒸气传输速率（WVTR）对涂层的防潮性能进行评价，并探究胶体

老化时间对涂层防潮性能的影响。结果表明，溶胶老化 30 h 时，涂层的 WVTR 最低，为 3.13 g/(m ·d)，具有优
异的防潮性能，且涂层光透明性好，附着力达到 0 级，铅笔硬度为 3H。

Abstract: Organic bridging silane precursor, 3-trimethonylsilylpropyl-2-methyl-3-[(3-trimethonylsilyl)-
propylsulfanyl]propionate were prepared by mercaptopropyl trimethoxysilane and 3-methylacrylloxypro-
pyltrimethoxysilane(MPMA) via thiol-ene click reaction. The sol was obtained by hydrolyzation and
condensation polymerization of MPMA under acidic condition through sol-gel method. Then, the organic-
bridged polysilsesquioxane coatings were fabricated by depositing the sol on glass slide through dip-coating
method and on polyetherimide through coating method, respectively. The moisture-proof performance of
coating was evaluated by measuring the water vapor transport rate (WVTR) and the effect of colloid aging
time on the moisture-proof performance of coating was investigated. The results showed that the coating
2
had the lowest WVTR, which was 3.13 g/(m ·d) when the sol aging time was 30 h. Moreover, the coating
possessed excellent moisture-proof performance and good optical transmittance. The adhesion was 0 grade
and the pencil hardness was 3H.
