【摘要】 研究了浓度为0.02mol/L的硝酸钠水溶液中非离子表面活性剂NP-10的相行为与流变学性质。随NP-10质量分数的增加,体系中依次可以形成胶束,六角状、立方状和层状液晶以及反胶束。六角状和立方状液晶的流变学性质可以用Maxwell模型说明。用已经验证的经验方程对层状液晶的流变学特征做出了表述。更多还原

【Abstract】 The phase behavior and rheological properties of NP-10 in 0.02 mol/L aqueous NaNO₃ solution were investigated.It was demonstrated that micelle,hexagonal,cubic,and lamellar liquid crystals and inverse micelle were formed successively in the same system as the mass fraction of NP-10 increased.The rheological properties of hexagonal and cubic liquid crystals are illustrated by Maxwell model,and the property of lamellar mesophase is explained by an empirical formula which has been validated in other cases.更多还原
