Sažetak:
General phase behavior of aqueous mixtures of dodecylammonium chloride, DACl, and sodium 4-(1-pentylheptyl) benzenesulfonate, NaDBS, confirms lyotropic properties of examined system. In the regions of equivalent mixtures and those with excess of NaDBS, curved (vesicles) or planar (lamellae) bilayer structures are formed, and in mixtures with DACl in excess spherical to ellipsoidal micelles are favored.Increment of surfactant concentration causes vesicles diameter growth and polydispersity, spontaneous transition of micelles via vesicles to lamellar, onion, and extremely large elongated tubular phases. Thermal properties of new catanionic complex dodecylammonium-4-(1-pentylheptyl) benzenesulfonate, DA-DBS, indicate organization of smectic bilayers composed of repetitive units of dodecylammonium cation and 4-(1-pentylheptyl) benzenesulfonate anion that are V-like packed and the dodecyl chains are tilted to the layer plain.
