| 摘 要： | 以甲基丙烯酸全氟辛基乙酯(PFEA)为含氟丙烯酸酯单体,烯丙氧基壬基酚聚氧乙烯(10)醚单磷酸(ANPEO10-P1)为反应型乳化剂,采用预乳化、半连续法聚合方式合成了具有核壳结构的无皂含氟丙烯酸酯共聚乳液。研究了乳化剂用量对聚合反应以及PFEA用量对乳胶膜吸水率和接触角的影响。结果表明,当反应型乳化剂ANPEO10-P1用量为5%(质量分数,下同),PFEA用量为6%时,得到的乳液粒径分布窄,稳定性好,乳液成膜后吸水率低,达到8.8%,对水的接触角达到了109.5°,表现出优异的疏水性能。

| Abstract: | The soap-free fluorine-containing acrylate copolymerization emulsion with core-shell structure was synthesized using 2-(perfluorooctyl)ethyl methacrylate(PFEA) as fluorinated acrylate monomer and ANPEO10-P1 as reactive emulsifier by pre-emulsification and semi-continuous polymerization method.The influence of emulsifier amount on polymerization process and PFEA amount on water absorbance and contact angle of emulsion film were investigated.The results show that the emulsion has good stability and narrow par... |
