| 摘 要： | 采用自由基乳液聚合的方法制备带有环氧基团的聚丙烯酸全氟烷基乙酯-甲基丙烯酸缩水甘油酯-苯乙烯无规共聚物P(FA-co-GMA-co-St),用红外光谱(FT-IR)和核磁共振(1H-NMR)对共聚物进行表征并将其用于环氧涂料的改性。XPS测试结果表明,带有环氧基团的含氟共聚物改性环氧涂层经蒸馏水浸泡48 h后接触角下降了15°为116°,表面氟元素含量下降了5.36%;而不带有环氧基团共聚物改性环氧漆膜经水浸泡48 h以后接触角下降了48°为88°,表面氟元素含量下降了7.94%。GMA单体的引入极大地提高了环氧涂层在湿润环境中的疏水性。

| Abstract: | A hydrophobic epoxy copolymer P(FA-co-GMA-co-St) was synthesized by free radicals emulsion polymerization.The copolymer was characterized by Fourier transform infrared spectrum(FT-IR) and 1H nuclear magnetic resonance spectrum(1H-NMR),the hydrophobic epoxy coating was prepared by blending the copolymers.The results of X-ray photoelectron spectroscopy(XPS) measurement show that contact angle of epoxy fluorinated copolymer modified epoxy coating decreases by 15° to 116° after 48h exposure in water and the surface fluorine element decreases by 5.36%.The contact angle of non-epoxy fluorinated copolymers modified epoxy coating decreases by 48° to 88° after 48h exposure in water and the surface fluorine element decreases by 7.94%.Epoxy copolymer improves environmental stability of the super-hydrophobic epoxy coatings. |
