以二甲基丙烯酸1,4-丁二醇酯(BDDMA)和3-巯基丙基三甲氧基硅烷(MPTMS)等为原料,经巯-烯点击反应制备前驱体有机桥连倍半硅氧烷(BD-BSQ)。将BD-BSQ和正硅酸四乙酯(TEOS)作为前驱体,添加一定量的碳量子点(CQDS),在乙酸的催化作用下进行水解-缩聚反应得到复合溶胶,最后将复合溶胶沉积在元件基底表面获得一系列防雾减反射复合涂层。探究了BD-BSQ前驱体添加量对复合涂层微观结构、光透过率、浸润性、防雾性能以及附着力的影响。结果表明当BD-BSQ与TEOS体积比为0.1∶3.9时,复合涂层最大透过率为97.9%,防雾效果优异,附着力等级可达0级。
The organic-bridged silsesquioxane precursor (BD-BSQ) was synthesized by the thiol-ene click reaction between 1,4-butanedioldimethylacrylate(BDDMA) and 3-merhydryltrimethoxysilane (MPTMS).The composite sols were obtained by the hydrolysis and condensation reactions between BD-BSQ and TEOS in the presence of carbon quantum dots (CQDs) under the catalysis of acetic acid.Finally,the composite sols were deposited on the substrates to obtain a series of antifogging and antireflective composite coatings.In this study,the influence of the proportioning of BD-BSQ and TEOS on the microstructure,light transmittance,wetting property,antifogging performance and adhesion of the composite coatings was mainly explored.When the volume ratio of BD-BSQ to TEOS was 0.1∶3.9,the maximum light transmittance of the coating was 97.9%,and the corresponding coating performed excellent antifogging property,with an adhesion rating of grade 0.
