摘要：本文以甲基丙烯酸(MAA)、甲基丙烯酸甲酯(MMA)、甲基丙烯酸全氟烷基乙基酯(FEMA)为单体,采用可逆加成-断裂链转移聚合法(RAFT),合成了含氟嵌段共聚物P(MMA-co-MAA)-b-PFEMA,并通过红外光谱、核磁共振、GPC等对产物结构进行了表征。同时还以甲苯、四氢呋喃(THF)、三氟甲苯(BTF)、三氟三氯(F113)乙烷为成膜溶剂制备了聚合物膜,研究了溶剂对膜表面结构和疏水性能的影响,其中甲苯所成膜的疏水性能最优,其接触角高达152.5°。
Wettability is an important property of solid surface and is governed by both the chemical composition and the geometrical micro-structure of the surface. Super-hydrophobic surfaces have attracted significant attention recently for both fundamental research and practical applications. In the paper, the copolymers were synthesized by reversible addition-fragmentation chain transfer （RAFT） in cyclohexanone with monomers methylmethacrylater （MMA）, methacrylic acid （MAA） and perfluoroalkyl ethyl methylacrylate （FEMA）. The structure of compound was confirmed by FT-IR spectra, 1H-NMR and MS. The micellization behavior of the block copolymer in toluene solvent was studied. Meanwhile, different hydrophobic surfaces were prepared by solvent evaporation-phase separa- tion process with different solvents such as toluene, tetrahydrofuran, benzotrifluoride and F113. And the contact an- gle of surfaces generated by toluene was 152.5°, which was significant for the preparation of the cost-effective, low- pollution.
