摘要: 本文以海藻酸钠(SA)和丙烯酰胺(AM)为基体，引入碳纳米管(CNT)和液态金属(LM)作为功能填料，用N,N'-亚甲基双丙烯酰胺作为交联剂，过硫酸铵为引发剂，采用自由基聚合相结合的策略，成功制备了具有优异导电性能的PAM/SA/CNT/LM双网络水凝胶。采用傅里叶红外光谱仪、力学拉伸机和数字万用表等对双网络水凝胶进行测试与表征。结果表明：液态金属的引入提高了双网络水凝胶的导电性且具有优异的力学性能，无水氯化钙进一步改善了水凝胶的抗冻抗脱水性。
Abstract: In this study, sodium alginate (SA) and acrylamide (AM) were employed as the matrix materials, with carbon nanotubes (CNT) and liquid metal (LM) innovatively incorporated as functional fillers. Using a free-radical polymerization strategy, we successfully fabricated a double-network conductive hydrogel fiber, PAM/SA/CNT/LM, with outstanding properties. During preparation, N,N'-methylenebisacrylamide was selected as the crosslinking agent, and ammonium persulfate served as the initiator, constructing a stable three-dimensional network structure. Systematic material characterization confirmed that the synthesized hydrogel possesses an ideal chemical structure and remarkable performance.
