利用乳液缩聚法制备芯材为氟硅烷（ FAS13）壁材接枝紫外吸收剂的二氧化硅微胶囊，将其与有机硅树脂乳液共混，涂覆于棉织物表面形成超疏水防紫外织物涂层。通过扫描电镜和透射电镜观察微胶囊的形态和粒径，并对涂层的水接触角和防紫外性能进行了测试，同时测试了涂层的耐老化、耐磨损、耐高温以及耐酸碱性。结果表明：织物涂层中微胶囊最佳含量为 45%（其中内含 6%紫外吸收剂），由此制备的涂层表面水接触角可达到 150°以上，并且具有较好的耐老化、耐高温、耐酸碱腐蚀、耐磨损等性能；同时该织物涂层具有优异的防紫外性，紫外线防护系数（UPF）可以达到 111.2。
Silicon dioxide microcapsules with fluorosilane（FAS13）as core material and silicon dioxide grafted with ultraviolet absorbent as shell were prepared by emulsion condensation polymerization. The microcapsules were blended with silicone latex，which was coated on the surface of cotton fabric to obtain a superhydrophobic and UV protective fabric coatings. The morphology and particle size of microcapsules were observed by SEM and TEM，and the water contact angle and UV protection performance of fabric coatings was tested. In the meantime，the weather resistance，wear resistance，high temperature resistance and acid and alkali resistance of coatings were also measured. The results showed that the best percentage of the microcapsules in fabric coatings was 45%（incorporated with 5% UV absobent），and the water contact angle of the prepared coating surface could reach higher than 150° . Moreover，the obtained fabric coatings provided good weather resistance，high temperature resistance，acid and alkali resistance and wear resistance. At the same time，the ultraviolet protection factor（UPF）of the fabric coatings could reach 111. 2，which showed excellent UV resistance.
