摘要

Surface-activity of a short-tailed chain hydrocarbon surfactant,heptane-1-sulfonic acid sodium salt(C_7SNa),was studied by using surface tension and conductivity measurements,which the surface-activity was improved largely by the addition of small amount of a fluorosurfactant,lH,lH,2H,2H,3H,3H,4H,4H-heneicosafluorotetradecylpyridinium iodine(HFTPI).The phase behavior and vesicle formation of C-H/C-F surfactant mixtures in aqueous solutions are similar to ones of cationic-anionic surfactant(catanionic)systems.The birefringent,viscoelastic La-phase consisting of unilamellar and multilamellar vesicles can be observed,which were determined by freeze-fracture transmission electron microscopy(FF-TEM)images.The Theological properties of La-phase samples were measured.~1H and ~(19)F NMR spectra were measured to monitor the information of self-assemblies of C_7SNa and HFTPI in L_1-phase(spherical micelles)and La-phase(vesicles).The results show that the C-H micelles and C-F micelles form in aqueous solutions individually.In La-phase(vesicles),the interaction between anionic hydrocarbon(C_7SNa)and cationic fluorocarbon(HFTPI)surfactants exist due to the strong electric static interaction of opposite charge head groups.
