| 英文摘要 | Surface-activity of a short-tailed chain hydrocarbon surfactant, heptane-1-sulfonic acid sodium salt (c7sna), 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, 1h,1h,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 l alpha-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 l alpha-phase samples were measured. h-1 and f-19 nmr spectra were measured to monitor the information of self-assemblies of c7sna and hftpi in l-1-phase (spherical micelles) and l alpha-phase (vesicles). the results show that the c-h micelles and c-f micelles form in aqueous solutions individually. in l alpha-phase (vesicles), the interaction between anionic hydrocarbon (c7sna) and cationic fluorocarbon (hftpi) surfactants exist due to the strong electric static interaction of opposite charge head groups.
