摘要:
通过一锅法制备了铁离子交联的羧甲基纤维素/聚［丙烯酸-（2-丙烯酰胺-2-甲基丙磺酸）］［CMC/P(AA-AMPS)-Fe3+］导电水凝胶，研究了CMC和AMPS含量对凝胶力学性能的影响，并使用万能拉伸试验机及数字万用表测试了该凝胶的自恢复性能和应变传感性能。结果表明，当CMC的质量分数为1.5%、AMPS质量分数为1.5%时，CMC/P(AA-AMPS)-Fe3+导电水凝胶综合力学性能最佳，此时CMC/P(AA-AMPS)-Fe3+导电水凝胶断裂强度为171 kPa，断裂伸长率为398%。当应变在0%~400%时，CMC/P(AA-AMPS)-Fe3+导电水凝胶的规范因子达到3.55。基于CMC/P(AA-AMPS)-Fe3+导电水凝胶的应变传感器能准确检测0%~500%的应变，能对人体不同尺度动作进行监测，且具有良好的循环稳定性。
Abstract:
An electrically conductive hydrogel of carboxymethyl cellulose/poly[acrylic acid-co-(2-acrylamido-2-methylpropane sulfonic acid)][CMC/P(AA-AMPS)-Fe3+] crosslinked with iron ions was prepared through a one-pot method. The influence of CMC and AMPS content on the mechanical properties of the hydrogel was investigated. Additionally，the self-recovery performance and strain sensing properties of the hydrogel were tested using a universal tensile testing machine and a digital multimeter. Results show that the CMC/P(AA-AMPS)-Fe3+ conductive hydrogel exhibits the optimal overall mechanical properties when the mass fraction of CMC is 1.5% and that of AMPS is 1.5%. At this composition，the hydrogel demonstrated a fracture strength of 171 kPa and fracture elongation of 398%. With strains ranging from 0% to 400%，the gauge factor of the CMC/P(AA-AMPS)-Fe3+ conductive hydrogel reaches 3.55. Utilizing the CMC/P(AA-AMPS)-Fe3+ conductive hydrogel as a base，the strain sensor accurately detects strains from 0% to 500%，enabling monitoring of various human movements while maintaining excellent cyclic stability.
