摘要
50℃下,测定了双十八烷基二甲基氯化铵(DODMAC)/n-C10H21OH/10%n-C10H22/H2O四元体系相图,确定了液晶区域范围,用^2H NMR方法,并辅以偏光显微镜照片,确定了液晶为反相六角状,用SAXS求出了液晶晶面间距,确定了晶面间距d1与含水量fw/(1-fw)之间的线性关系,并求得圆柱形聚集体的直径ds=4.035nm。
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.
