摘要: Abstract The existence of vesicles composed synthetic cationic surfactant, dioctadecyldimethylammonium chloride (DOAC) alone was confirmed by electron microscopy and supported 13 C- 1 H-nmr spectroscopy. single bilayer multilamellar obtained ultrasonication were found to resemble very closely the patterns those natural phospholipids be stable for at least 3 months, once formed. It also from results sonication time dependence viscosity electrical conductivity that vesicle formation DOAC not easier than phospholipids. line widths (CH 2 ) n N + protons in bilayers decreased with increasing temperature, but a discontinuous change linewidth (abrupt broadening) observed transition temperature ( T c region (43–48°C). result suggests hydration behavior below is different above . apparent activation energy ∗ relaxation data order potential barrier internal rotation CC or CN bond.
