| Abstract: | The measurements of 2H NMR gave three reasons for the decrease of the stability of lamellar liquid crystal in SDS/C10OH/solvents when formamide was used as the solvent instead of waters the order parameter of SDS and C10OH decreased, the degression of order parameter of SDS and C10OH along the carbon chain increased and the compatibility of SDS with C10OH decreased. The low angle X-ray measurements show that the permeability of the solvent in the lamellar liquid crystal was increased when water was replaced by formamide so that the interlayer spacing d decreased at a certain weight ratio of C10OH/SDS and the dependence of the interlayer spacing d on the weight ratio of SDS/C10OH changed. |
