在研究壳聚糖醋酸水溶液粘度行为的实验基础上,研究了前人提出的描述聚电解质溶液粘度与浓度经验关系的适用性,并且提出了一套较为合理的常数确定方法。同时提出了一个新的经验式,该经验式不仅浓度适用范围较宽,而且能适用于其他类型的聚电解质溶液体系。文中还讨论了柔性链聚电解质溶液粘度行为与刚性链聚电解质溶液粘度行为的差别以及产生这种差别的原因。 Based on the experimental study on the viscosity behavior of chitosan acetate aqueous solution, the applicability of the empirical relationship between the viscosity and the concentration of polyelectrolyte solution proposed by the predecessors was studied. A more reasonable method of determining the constant was proposed. At the same time, a new empirical formula is proposed. The empirical formula not only has a wide range of concentration but also can be applied to other types of polyelectrolyte solution systems. The paper also discusses the difference between the viscosity behavior of the flexible chain polyelectrolyte solution and that of the rigid chain polyelectrolyte solution and the reason for the difference.
