Abstract: Lyotropic liquid crystals formed from mixed surfactants perfluorooctanoic sodium/hexadecyltrimethyl ammonium bromide(OBS/CTAB-H2O-C4H9OH) have been used to determine the phase regions. The area of phase region in present system was bigger than that in CTAB C4H9OH H2O system. Some typical photographs were obtained by polarized light microscope. The geometrical dimensions were determined by small angle X-ray diffraction. The 2H NMR method together with liquid crystals photographs were applied to determine the exact liquid crystals' structure.
Key words: perfluorooctanoic sodium, hexadecyltrimethyl ammonium bromide, mixed surfactant system, crystal texture, small angle X-ray diffraction, 2H NMR
