The lytropic liquid crystals in dodecanic acid diethanolamine (DAD)/n-butanol (C₄OH)/octane (n-C₈H₁₈)/deuteron (D₂O) system were studied to determine the phase regions and were investigated by ²H-NMR spectroscopy,optical polarizing microscope and small-angle X-ray diffraction (SAXD) methods.The results indicate that the lamellar,hexagonal and cubic liquid crystals all exist in the above system.Keeping the weight ratio of DAD and C₄OH constant,the microphase structure,²H quadruple splitting and the interlayer spacing are all changed with the addition of deuteron.
