摘要

为解决现有可拉伸电极存在的制备工艺复杂和本征可拉伸性能差的问题，采用简单的原位聚合方法，通过优化掺杂剂，开发了一种具有本征可拉伸性的聚吡咯基导电纤维. 在导电纤维的制备过程中，磺基水杨酸钠被用作掺杂剂和增塑剂，使得导电纤维展现出出色的初始电导率(6.34 S/cm)，并且在100%拉伸应变下仍保持5.37 S/cm的良好导电性能. 此外，基于弹性导电纤维的加热器具有优秀的焦耳热性能. 当施加5 V电压时，其表面温度可达到60 ℃，为热疗提供了可靠的加热效果. 进一步将导电纤维集成到电热手套中，实验发现在手指关节运动过程中，手套表面温度仅下降了4.89%，可实现对运动关节的稳定热疗. 这为雷诺综合征和关节损伤疼痛等疾病的物理治疗提供了便捷有效的实施方案.

Abstract

To solve the problems of complicated preparation process and poor intrinsic stretchability of existing stretchable electrodes

this study employs a simple

in situ

polymerization method and optimizes the dopant to develop a conducting polypyrrole-based fiber with excellent intrinsic stretchability. Sodium salicylate is utilized as both a dopant and a plasticizer during the fabrication process

resulting in a highly conductive fiber with an initial conductivity of 6.34 S/cm

which remains at 5.37 S/cm even under 100% strain. Furthermore

the elastic conductive fiber-based heater exhibits excellent Joule heating performance. When a 5 V voltage is applied

the surface temperature can reach 60 ℃

providing reliable heating effects for thermotherapy. Moreover

when integrating the conductive fibers into electric heating gloves

experimental results show that the surface temperature of the gloves only decreases by 4.89% during finger joint movements

enabling stable thermotherapy for moving joints. This provides a convenient and effective implementation for the physical treatment of conditions such as Raynaud's syndrome and joint injury pain.
