| 摘 要： | 在十二烷基苯酸钠（ＮａＤＢＳ）和正庚烷水溶液中分别加入脂肪醇和ＮａＣｌ时，研究了体系中的相态结构和相转变的规律。在较高浓度的 ＮａＤＢＳ体系中长链醇（从正戊醇到正辛醇）促使层状液晶相的形成，短链醇如正丁醇和正丙醇的加入则无液晶态结构出现．ＮａＣｌ的加入引起液晶相的形成．

| Abstract: | The optical textures and the transition from anisotropic liquid crystalline phase to isotropic phase was investigated by adding respectively alcohols and sodium chloride to aqueous solution of sodium dodecyl benzene sulfonate(NaDBS) and n-heptane. At relatively higher concentrations of NaDBS where the long chain alcohols(from n-pentanol to n-octanol) promotes the formation of lamellar liquid crystalline phase but no evidence of appearance of liquid crystalline phase when applying short-chain alcohols such as n-butanol and n-propanol. Addition of NaCl causes the liquid crystalline phase to form. |
