摘　　要：采用二甲基二氯硅烷对ITO薄膜中的纳米SiO2进行表面亲油改性，考察其在丙烯酸树脂中的分散性能及其对体系的影响。结果表明：改性后的纳米SiO2粒径分布均匀，分散性好；经高速和超声分步分散后，SiO2添加量为2％～3％的体系透光率最低，稳定性最好。Surface lipophilic modification of nano-SiO2 in ITO film with dichlorodimethylsilane is made. The dispersity of the modified nano-SiO2 in acrylic resin and its effect on the dispersion system is investigated. The results show that the modified nano-SiO2 has a uniform particle size distribution. The transmittance of the system with 2%-3% SiO2 ,which is dispersed by high speed first and then ultrasonic wave,is the minimum and its stability is the highest.
