中文摘要:
      本研究以氯化胆碱/乙二醇低共熔溶剂(DES)、丙烯酰胺(AM)、聚吡咯/纤维素纳米纤维复合物(PPy/CNF)及单宁酸为原料,制备兼具优异力学性能、导电性能、抗冻性能、黏附性能与应变传感性能的复合导电凝胶DES-PPy/CNF-PAM,重点探究PPy/CNF的质量分数对复合导电凝胶的性能影响。结果表明,当PPy/CNF质量分数为1.5%时,复合导电凝胶综合性能最优,其断裂应变可达910%,室温电导率为1.234 S/m,分别是未添加PPy/CNF的凝胶的3.8和4.8倍;同时,此复合导电凝胶对多种基质具有优异的黏附性能,且具有可靠的应变传感性能,在-40 ℃低温环境下仍可维持良好的柔韧性与稳定的导电能力。
Abstract:
      In this study, composite conductive gel DES-PPy/CNF-PAM with excellent mechanical, conductive, antifreezing, adhesive and strain-sensing properties was fabricated using choline chloride/ethylene glycol deep eutectic solvent (DES), acrylamide (AM), polypyrrole/cellulose nanofiber composite (PPy/CNF) and tannic acid as raw materials. The effect of the mass fraction of PPy/CNF on the performances of the composite conductive gel was systematically investigated. The results showed that the composite conductive gel achieved optimal comprehensive performances at a PPy/CNF mass fraction of 1.5%. Its fracture strain reached 910%, and the room-temperature conductivity was 1.234 S/m, which were 3.8-fold and 4.8-fold those of the gel without PPy/CNF, respectively. Meanwhile, this composite conductive gel exhibited outstanding adhesion to diverse substrates and reliable strain-sensing capability. It could still maintain favorable flexibility and stable conductive capacity even at an ultra-low temperature of -40 ℃.
