摘要：In this paper, we report a micelle-to-vesicle transition in aqueous :solution of the anionic single-tailed surfactant (STS) Whim dodecylbenzenesulfonate :(SDBS), with the mediation of a rough glass surface (RGS) in the absence of cosurfactants or additives. This transition produced a mixed solution of vesicles and,micelles. Interestingly, the obtained SDBS vesicles in the :solution displayed good stability during a long-term storage (at least 6 months at room temperature), exposure to high temperature (80 degrees C for 2 h), and freeze-thawing- (-20 or 196 degrees C for 2 h to approximately 25 degrees C) after the RGS,was removed., Our results::Confirmed. that SDBS could adsorb on the RGS to form-bilayers; in which the Molecular packing parameter of SDBS was in the range of 1/2-1. The,bilayer adsorption and the roughness, of the solid surface played an important role in vesicle formation: In addition, we propose a possible mechanism for the RCS-mediated transition of micelle-to-vesicle in SDBS solutions : SDBS. micelles and molecules adsorb On the RGS to form curved bilayers; the curved bilayers detach from the RGS, and then close to forth vesicles.
