【摘要】 把膨润土/聚丙烯酸钠超吸水性复合材料浸入到电解质溶液中,制备了一种电导率为50 S.m-1的新型水凝胶电解质.实验表明,水凝胶电解质具有类似离子溶液的电导率,水凝胶电解质的电导率主要决定于它所浸入溶液的离子浓度、pH值和温度.超吸水性复合材料的吸水倍率对水凝胶电导率是具有重要的影响,但在一定的范围内,超吸水性复合材料的制备条件对水凝胶的电导率的影响较小.更多还原

【Abstract】 A novel hydrogel electrolyte with conductivity at 50 S·m^-1 was prepared by immersing poly-sodium acrylate/bentonite superabsorbent into an electrolyte aqueous solution.The resulted hydrogel electrolyte behaved like liquid in term of ionic conductivity,and the conductivity of the hydrogel electrolyte mainly depends on the ionic intensity,the pH value and temperature of.The water absorbency of superabsorbent has a great impact on the conductivity of the hydrogel electrolyte.But within certain range of extent,the preparation condition of superabsorbent has a slight influence on the conductivity of the hydrogel electrolyte.更多还原
