采用水－乙醇混合溶剂法制备了聚丙烯酸锂与正离子表面活性剂复合材料。该复合材料由于表面活性剂的引入，结晶取向得到了提高，从而使其机械性能和离子电导率也有较大改善，即随着表面活性剂的用量不同，结晶与离子电导率亦不同。并通过电化学交流阻抗谱及非线性最小二乘拟合法对此体系进行了分析和模拟。 Poly (lithium acrylate) and cationic surfactant composites were prepared by water-ethanol mixed solvent method. Due to the introduction of the surfactant, the crystal orientation of the composite material is improved, so that the mechanical properties and ion conductivity of the composite material are also greatly improved. That is to say, with the different amounts of the surfactants, the crystallinity and ionic conductivity are also different. The system was analyzed and simulated by electrochemical impedance spectroscopy and nonlinear least squares fitting.
