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.
