| 英文摘要 | The interfacial property of cationic ammonium gemini surfactants with the structure of [C(12)H(25)(CH(3))(2)N(CH(2))(S)N(CH(3))(2)C(12)H(25)]Br(2) (S=3, 4, 6, 10, and 12), referred to as C(12)C(S)C(12)Br(2), has been studied at the n-heptane/water interface as a function of the surfactant concentration. The interfacial tension vs surfactant concentration curves show an apparent minimum for the homologues with S >= 6. This behavior may be resulted from conformational and location changes of the spacer adsorbed at the interface due to its flexibility as well as the hydrophobic environment provided by the sublayer composed of gemini surfactant aggregates. In addition, the interfacial tension at the interface between n-heptane and the aqueous solution of C(12)C(6)C(12)Br(2) with polyacrylamide (PAM) and hydrophobically modified polyacrylamide (HMPAM) has been studied to aid the understanding on the adsorption mechanism proposed for the abnormal interfacial behavior of C(12)C(S)C(12)Br(2) surfactants. The interfacial tension is reduced significantly by the C(12)C(6)C(12)Br(2)/PAM mixture at very low concentration of C(12)C(6)C(12)Br(2). For C(12)CrC(12)Br(2)/HMPAM, no minimum is shown in the interfacial tension curve and poorer efficiency in reducing interfacial tension is observed. (C) 2010 Elsevier B.V. All rights reserved. |
