摘要

The current study introduces the water-soluble complexes containing hydrophobically associating copolymer and a series of surface activity imidazolium-based ionic liquids (C(n)inimBr, n = 6, 8, 10, 12, 14 and 16). The polymer, denoted as PAAD, was prepared with acrylamide (AM), acrylic acid (AA) and N,N-diallyl-2-dodecylbenzene sulfonamide (DBDAP). And the hydrophobic associative behavior of PAAD was studied by a combination of the pyrene fluorescence probe and viscosimetry. Incorporation of C(n)mimBr (n = 10, 12, 14 and 16) in PAAD leaded to the white thick gel, while the pellucid solutions were obtained in complexes of PAAD and C(n)mimBr (n = 6 and 8); addition of C(6)mimBr around critical micelle concentration resulted in a large decrease in viscosity of solution. Therefore, we particularly investigated the performance of PAAD/C(8)mimBr complex. The interfacial tension of PAAD/C(8)mimBr complex solution and crude oil under different conditions was examined. Moreover, PAAD/C(8)mimBr complex exhibited
