以甲基丙烯酸甲酯(MMA)、甲基丙烯酸十八酯(SMA)、甲基丙烯酸-β-羟乙酯(HEMA)、2-(全氟辛基)乙基甲基丙烯酸酯(FMA)为单体,采用自由基溶液聚合方法合成了含氟甲基丙烯酸酯树脂.将无机纳米二氧化硅(SiO2)粒子掺杂到该树脂中,通过交联固化得到含氟甲基丙烯酸酯树脂/SiO2复合液.利用傅里叶变换红外光谱(FT-IR)、X射线光电子能谱(XPS)与场发射扫描电子显微镜(FESEM)对涂层结构进行了表征.以不锈钢板为底材,讨论了二氧化硅粒子加入量和复合液浓度对复合涂层表面润湿性的影响.结果表明,当二氧化硅占含氟甲基丙烯酸酯树脂质量的20％,所制含氟甲基丙烯酸酯树脂/SiO2复合液的浓度为5％时,在不锈钢基材上制备的复合涂层对水的静态接触角达到126.7°,对煤油的静态接触角为26.8°.
