摘　　要：采用半连续加入乳液聚合的方法合成了含不同长度氟碳链的丙烯酸酯-丙烯酸共聚物。通过傅里叶变换红外光谱(FT-IR)和热重分析(TGA)对聚合物的组成、热稳定性等性质进行了表征,详细考察了不同氟碳链对聚合物性质的影响。经聚合物乳液整理后织物的水接触角和二碘甲烷接触角显示出织物表面具有良好的疏水疏油性,与长氟烷基链聚合物相比有相同的特性;此外,接触角、荧光显微镜以及元素面分布结果表明,整理后的织物具有疏水/疏油-亲水性转换功能,这对于织物的抗污及清洗具有良好的作用。Novel poly（perfluoroalkylated acrylate-acrylic acid） [P（PFAA-AA）] copolymers were prepared by the emulsion copolymerization of short chain perfluoroalkyl-containing acrylate with acrjlic acid. Copolymers were characterized with FT-IR and their thermal stabilities were studied by TGA. These copolymers were used to treat cotton fabrics. A smart surface switching from olephobic/hydrophobic to hydrophilic on treated fabrics was observed. The change behavior of oleophobicity/hydrophobicity to hydrophilicity was investigated by elemental map and fluorography. The mechanism of smart surface was proposed.
