摘　　要：以聚乙烯醇(PVA)为水凝胶基质材料,氯化锂(LiCl)为导电物质,甘油-水混合物为溶剂,通过物理交联法制备PVA/LiCl复合水凝胶材料。对水凝胶材料的断面形貌、化学结构、晶体结构、力学性能和电导率进行测试分析。测试结果表明:PVA水凝胶中加入LiCl可以明显提高电导率;随着LiCl质量分数增大,复合水凝胶的电导率增大,力学性能下降。PVA/LiCl ydrogel materials are prepared by physical crosslinking method with polyvinyl alcohol as hydrogel matrix material,lithium chloride as conductive material,and glycerol water mixture as solvent.The cross section morphology,chemical structure,crystal structure,mechanical properties,and conductivity of the hydrogel materials are tested and analyzed.The research shows that the addition of lithium chloride in PVA hydrogel can significantly improve the conductivity of the hydrogel.With the increase of LiCl content,the conductivity of the composite hydrogel increases,while the mechanical properties decline.
