摘要
聚（丙烯酸－丙烯酰胺）－碱金属盐复合物是一种新型高分子固体电解质。文中详细讨论了离子种类、盐浓度、增塑剂种类和用量以及温度等因素对其电导率的影响。结果表明，不同碱金属盐对电解质电导率的影响因其阳离子半径、晶格能、离子淌度以及在电解质中的溶解度的不同而不同；电导率的盐浓度依赖性因电解质的离子传导方式不同而明显呈现双峰形；增塑剂对电导率的影响则因其作用方式不同而产生不同的效果；电导率的温度依赖性也因电解质的离子传导方式不同而呈现不同的规律。
Poly(acrylic acid acrylamide) alkali metal salt complex is a new kind of solid polymer electrolytes. Effect of kind of ion, salt concentration, kind and amount of plasticizer and temperature on conductivity were discussed in detail. The results show that effects of alkali metal salts on conductivity are different because of their different anion radium, crystal lattice energy, ionic mobility and solubility in electrolytes, that different ionic conduction modes of electrolytes result to double peak of salt concentration dependence of conductivity and different temperature dependence, and that different influences of plasticizer to conductivity result from their different action.
