摘　　要：采用三元乳液聚合方法,选用丙烯酸十三氟辛酯作为含氟单体,并以甲基丙烯酸甲酯和苯乙烯作为辅助单体在水中进行自由基共聚制得含氟共聚物(FP)乳液。在对其结构性能和微观形貌进行研究的基础上,将FP整理在不同纤维织物基材上。利用红外光谱、电子显微镜及接触角等手段研究了高聚物的表面形貌,考察了织物在整理前后的静态接触角、耐水洗性及透湿性等性能的变化。结果表明,FP膜具有纳米尺寸;整理的棉、涤纶、涤棉、锦纶和羊毛织物具有良好的超疏水性能;完成30次皂洗后,涤纶、锦纶和羊毛织物相比于棉和涤棉织物仍表现出较好的疏水效果。The ternary element emulsion polymerization method was used in this paper. Tridecafluorooctyl acrylate (PFOA) was selected as fluoromonomer and free-radical copolymerization was carried out in water with methyl methacrylate (MMA) and styrene (St) as auxiliary monomers to prepare fluorocopolymer (FP) emulsion. Based on the study of its structural properties and microstructure, the FP was finished on different fiber fabric substrates. The surface morphology of polymer was studied by infrared spectroscopy, contact angle and etc. The changes of static contact angle, water washing resistance and moisture permeability were investigated before and after finishing. The results show that the FP film is a polymer film with nanoscale size. The finished cotton, polyester, polyester/cotton, nylon and wool fabrics all have super-hydrophobic effects. After washing 30 times, the finished polyester, nylon and wool fabrics still show good hydrophobic effect, but the hydrophobic effects of cotton and polyester/cotton fabrics are not ideal.
