研究了阳离子碳氢表面活性剂十二烷基三烷基溴化铵[C12H25N(CnH2n＋1)3Br, n＝1, 2, 3, 4]和阳离子碳氟表面活性剂F[CF(CF3)CF2O]2CF(CF3)CONH(CH2)3N(C2H5)2CH3I (FCI-2)分别与中性高聚物聚氧乙烯(PEO, 分子量20000)和聚氧乙烯-聚氧丙烯三嵌段共聚物[(EO)76(PO)29(EO)76, F68]的相互作用. 结果表明, 所用的碳氢阳离子表面活性剂与PEO和F68均无相互作用, 但碳氟阳离子表面活性剂FCI-2与PEO和F68均具有明显的相互作用, 而且F68与FCI-2的相互作用强于PEO与FCI-2体系. 结果也初步表明碳氟表面活性剂与高聚物的相互作用强于碳氢表面活性剂-高聚物体系.

This work investigated the interactions of cationic hydrogenated/fluorinated surfactants dodecyltrialkylammonium bromide [C12H25N(CnH2n＋1)3Br, n＝1, 2, 3, 4] and F[CF(CF3)CF2O]2CF(CF3)- CONH(CH2)3N(C2H5)2CH3I (FCI-2) with polyethylene oxide (PEO, Mn＝20000) and block copolymer [(EO)76(PO)29(EO)76, F68], which showed that there was no interaction between dodecyltrialkylammonium bromide and PEO or F-68. However, significant interactions were observed between FCI-2 and both PEO and F68, and F68 exhibited stronger interaction with FCI-2 than PEO did. These results suggested that the cationic fluorinated surfactants had stronger interaction with neutral polymers than the cationic hydrogenated surfactants.

Key words: dodecyltrialkylammonium bromide, fluorinated surfactant, polymer, polyethylene oxide, block copolymer
