Simple and composite membranes have been prepared from 2% collodion solutions containing different amounts of polystyrenesulfonic acid (PSSA). Various membrane parameters such as water content, electrolyte uptake, exchange capacity, and permselectivity of these membranes have been determined. The resistance and capacitance of simple membranes have been measured as functions of both external electrolyte concentration and internal fixed charge density. The impedance characteristics of composite membranes also have been determined and discussed in terms of the resistance and capacitance characteristics of simple membranes from which the composite structures have been formed.
已由含有不同量聚苯乙烯磺酸(PSSA)的2%火棉胶溶液制备了简单膜和复合膜。已测定了这些膜的各种膜参数,如水含量、电解质吸收量、交换容量和渗透选择性。已测量了简单膜的电阻和电容与外部电解质浓度和内部固定电荷密度的函数关系。还根据形成复合结构的简单膜的电阻和电容特性,确定并讨论了复合膜的阻抗特性。
