摘　　要：以γ-甲基丙烯酰氧基丙基三甲氧基硅烷(MPTMS)、N-甲基全氟辛基磺酰基胺基丙烯酸乙酯(MPSAEA)、甲基丙烯酸甲酯(MMA)共聚,然后利用原位复合技术引入纳米SiO2微粒,制备了均匀透明的SiO2纳米复合含氟聚合物材料。用红外光谱(FT-IR)、透射电镜(TEM)和电子衍射(ED)等表征了复合材料的形貌和结构。将聚合物用做涂层材料,用扫描电镜(SEM)、X-射线光电子能谱(XPS)、接触角测定仪和显微硬度仪测定了涂层的形貌、涂层表面的化学成分、涂层与水的接触角随时间的变化、涂层的硬度变化,结果表明纳米复合聚合物可在玻片表面形成均匀光滑的涂层,涂层表面纳米SiO2和含氟成分共同存在,纳米SiO2复合涂层在室外放置半年以后仍保持良好的疏水性,并且纳米复合聚合物涂层的硬度随含氟单体含量的增加而增加。The title uniform and transparent coatings has been prepared by copolymerization of γ-methylpropionyloxy propyl trimethoxy silane (MPTMS),N -methyl perfluorooctyl sulfonamide ethyl acrylate (MPSAEA) and methyl methacrylate ( MMA) , then incorporated with nano -SiO2 by in-situ hybrid technology. The morphology and structure of the hybrid material is characterized by use of FT-IR, TEM and ED. The morphology, chemical composition of film surface, variation of contact angle with water versus time and changes of hardness of the polymer coatings film are characterized by use of SEM,XPS, contact angle tester and micro hardness tester. It has shown that the nano - SiO2 hybrid polymer can form an uniform and smooth film on glass,with coexisting of nano-SiO2 and fluoro component on coatings surface. The hybrid coatings keeps good hydrophobic performance after half year outdoor exposure. The hardness of the coatings film increases with increase of amount of fluoromonomer.
