| 摘 要： | 以异佛尔酮二异氰酸酯(IPDI)、十二氟庚醇(FOH)、烯丙基聚乙二醇(APEG)合成的表面活性含氟单体(FSM)与丙烯酰胺通过水溶液聚合,制备出含氟疏水缔合聚丙烯酰胺(FPAM).用表面张力法研究了FSM的胶束化,用流变仪、动态激光光散射(DLS)和原子力显微镜(AFM)表征了FPAM溶液的流变性能、缔合结构尺寸和形态.结果表明,FSM在25℃下CMC为1.28 g.L-1,表面张力为26.77 mN.m-1.FPAM溶液属于假塑性体系,临界缔合浓度为0.660%,具有一定的耐盐性.DLS和AFM表明,在低于临界缔合浓度时FPAM溶液仍能产生大量的缔合结构,FPAM分子具有很强的疏水缔合性.

| Abstract: | In order to eliminate the disadvantageous effect of surfactant on relative molecular mass and post-treatment in preparing fluorinated hydrophobically associating polyacrylamide(FPAM) by free radical micellar copolymerization and to increase compatibility of fluorinated monomer and AM,fluorinated surface-active monomer(FSM) was synthesized by IPDI,dodecafluoroheptanol(FOH) and allyl polyethylene glycol(APEG) and copolymerized with AM by aqueous solution polymerization,then FPAM was achieved without post-trea... |
