Abstract

The equilibrium phase diagram for the system dioctadecyldimethylammonium chloride (DODMAC)/n-decanol/n-decane/water was determined at 50 ℃. The hyperfine structures of the liquid crystal phase were studied by 2H NMR, X-ray low-angle diffraction, and polarizing microscopy. All results showed that there was a reversed hexagonal liquid crystalline phase. The connection between crystalline face distance (d1) and the content of water [fw/(1-fw)] was obtained and the diameter of the cylindrical assemble was getted to be 4.035nm.

Key words: LIQUID CRYSTAL, PHASE DIAGRAM
