Title: Time-Resolved SAXS Spectra after Rapidly Mixing Anionic and Cationic Surfactants

Abstract

The temporal evolution of nano-structures in mixing the aqueous solutions of anionic and cationic surfactants was investigated by measuring time-resolved SAXS spectra. It is found that vesicles formed just after mixing annihilate to be followed by the lamella formation. The peak intensity due to the vesicle structure decays exponentially with an elapsing time. The peak intensity assigned to the lamella structure grows with a power law of time. The decay time of vesicle and the exponent of power function of time describing the lamella growth increase with NaCl concentration. These results indicate that the electrostatic interaction affects the stability of nano-structures.
