摘　　要：选取十二烷基硫酸钠(SDS),辛基苯基聚氧乙烯醚(OP-10)为复合乳化剂,过硫酸钾(KPS)为引发剂,将2-(全氟己基)乙基甲基丙烯酸酯(PFM)与丙烯酸酯类单体采用预乳化-半连续种子乳液聚合法进行乳液共聚,再将羟基螺吡喃(SPOH)与乳液进行物理共混,制得光致变色含氟丙烯酸酯乳液。通过多种表征手段研究丙烯酸正丁酯(n-BA)和甲基丙烯酸甲酯(MMA)软硬单体的质量比,SPOH的用量对聚合反应和乳胶膜性能的影响。结果表明,加入含氟单体后乳胶膜与水、油的接触角提高,热稳定性提高;加入SPOH的质量分数为1. 25%时,乳胶膜具有较好的光致变色性能。The fluorine modified acrylate emulsion polymerization was performed using sodium dodecyl sulfate（SDS） and octylphenyl polyoxyethylene ether（OP-10） as complex emulsifiers, 2-（perfluorohexyl） ethylmethacrylate （PFM） as the fluorinated acrylate monomer, and potassium persulfate（KPS） as the initiator. Spiropyran was physically blended with the emulsion to obtain a photochromic fluorinated acrylate emulsion. The effects of the mass ratio of methyl methacrylate（MMA） to butyl acrylate（BA） monomers, and the amount of hydroxyspiropyran（SPOH） on the polymerization and the properties of the latex films were studied by means of various spectroscopic methods. The results show that the contact angle and thermal stability of the fluorinated polyacrylate are improved. The film presents good photochromic properties with addition of 1.25%（mass fraction） spiropyran.
