摘要:
为提高导电水凝胶的机械强度、抗疲劳稳定性等性能,采用预拉伸工艺制备高强韧和耐磨离子导电水凝胶。以兼具生物相容性和力学柔韧性的黄原胶(XG)和聚乙烯醇(PVA)为主要原料,通过冷冻、预拉伸和柠檬酸钠(Na 3Cit)浸泡盐析的方法制备导电水凝胶,使其具有双网络结构;优化预拉伸工艺参数,并将导电水凝胶精心制成柔性传感器,探究其传感响应能力。结果表明:当预拉伸比由0增加到5%时,所制备的导电水凝胶拉伸断裂强度由3.0 MPa提升到7.5 MPa,耐磨性能从5.0 MPa提升至6.0 MPa,导电性能也从0.05 S/m提升至0.75 S/m,所得导电水凝胶能很好地应用于人体交互系统,对人体喉咙吞咽、腕关节弯曲、指关节弯曲都能有效监测。预拉伸作用有效提高了导电水凝胶分子链的各向同性,同时提高了导电水凝胶的力学性能、耐磨性能和导电性能。该研究可为导电水凝胶在智能可穿戴柔性传感器领域中的应用提供基础。
