以乙烯基功能化的SiO2粒子(Vinyl-SiO2)为种子,苯乙烯(St)和甲基丙烯酸十三氟辛酯(FOMA)为共聚单体,通过乳液聚合法制备了SiO2/舍氟聚合物(SiO2/PFS)复合材料.采用傅里叶变换红外光谱、扫描电镜、透射电镜等方法对产物的化学组成及形态进行了表征.结果表明,含氟聚合物成功接枝在SiO2粒子的表面,SiO2/PFS复合材料呈不规则的核壳结构.对SiO2/PFS复合材料进行水接触角测定,结果显示,FOMA的用量对SiO2/PFS复合材料的疏水性有较大的影响.当m(FOMA)/m(St) =0.3时,SiO2/PFS复合材料在1～14的pH范围内具有很好的化学稳定性,且接触角高达171°.
