Nanocomposite polymer films are prepared by using ultrasonic spray deposition (USD) technique through mixing polymethyl methacrylate as matrix and fumed silica nanoparticles as second phase in dimethyl carbonate solvent. Annealing procedure improves the film uniformity and optical transmission. The addition of fumed silica nanoparticles impedes the transmission of the electrolyte films due to agglomeration of fumed silica nanoparticles. Fortunately, adding surfactant, cetyltrimethylammonium bromide, disperses the fumed silica nanoparticles and retrieves the optical transmission of nanocomposite polymer films to around 90%. The hardness and elastic modulus of the nanocomposite polymer films are better than the commercial bulk. The USD deposited nanocomposite polymer film comprises of PMMA and fumed silica nanoparticles is a promising candidate of solid‐state electrolyte for EC windows application. POLYM. ENG.

基于聚甲基丙烯酸甲酯（PMMA）和气相二氧化硅纳米粒子的纳米复合薄膜的光学和力学性能

纳米复合材料聚合物薄膜是通过使用超声喷涂沉积（USD）技术，将聚甲基丙烯酸甲酯作为基质和气相二氧化硅纳米颗粒作为第二相在碳酸二甲酯溶剂中混合而制得的。退火程序改善了膜的均匀性和光透射率。由于气相二氧化硅纳米颗粒的团聚，气相二氧化硅纳米颗粒的添加阻碍了电解质膜的传输。幸运的是，加入表面活性剂十六烷基三甲基溴化铵可分散气相二氧化硅纳米颗粒，并使纳米复合聚合物薄膜的光学透射率恢复到90％左右。纳米复合聚合物膜的硬度和弹性模量比市售的块体好。美元沉积的纳米复合聚合物膜包含PMMA和气相二氧化硅纳米颗粒，是用于EC窗应用的固态电解质的有前途的候选者。POLYM。ENG。SCI。，60：553–557，2020.©2019塑料工程师协会
