摘要
论文考察了1-癸基-3-甲基咪唑硝酸盐、水、正己醇三元体系中的溶致液晶相聚集行为。研究表明,烷基取代的咪唑硝酸盐可以在水溶液中自聚集形成六角状溶致液晶体系,且上述六角相可以容纳少量的正己醇而不改变其相态结构。当正己醇含量进一步增加时,上述三元体系中出现了六角状溶致液晶向层状溶致液晶体系的转变。正己醇在上述相变过程中发挥了助表面活性剂的作用。
Lyotropic liquid crystalline phase in ternary system composed by 1-decanol-3-methylimidazolium nitrate([C_(10)Mim][NO_3]),water and hexanol is investigated.Hexagonal phase can be obtained in the[C_(10)Mim][NO_3]aqueous solution at 25℃.With small amount of hexanol,the above hexagonal phase can be retained.Lamellar phase can be found in this ternary system with proper addition of hexanol.Influence of factors,like concentration,temperature,and co-surfactant,is discussed.
