Abstract

Conductive polymer composites (CPCs) are widely used in the flexible strain sensors due to their simple fabrication process and controllable sensing properties. However, temperature has a significance impact on the strain sensing performance of CPCs. In this paper, the strain sensing characteristics of MWCNTs/PDMS composites under temperature loading were systematically studied. It was found that the sensitivity decreased with the increase of temperature and the phenomenon of shoulder peak also decreased. Based on the theory of polymer mechanics, it was found that temperature could affect the conductive network by changing the motion degree of PDMS molecular chain, resulting in the change of sensing characteristics. Finally, a mathematical model of the resistance against loading condition (strain and temperature), associated with the force-electrical equivalent relationship of composites, was established to discuss the experimental results as well as the sensing mechanism. The results presented in this paper was believed helpful for the further application of strain sensors in different temperature conditions.

摘要

导电聚合物复合材料由于其制造工艺简单和传感性能可控性强的优势而被广泛应用于柔性应变 传感器的制造。然而, 温度会对导电聚合物复合材料的应变传感性能产生巨大的影响。本文研究了 MWCNTs/PDMS 复合材料在不同温度加载条件下的应变传感性能。结果表明, 应变传感器的灵敏度 会随着温度的升高而提高, 而且肩峰现象也会随之减弱。根据聚合物力学理论, 温度能够通过改变 PDMS 分子链的运动程度来影响复合材料的导电网络, 且最终导致复合材料的传感性能变化。最后, 结合复合材料的力电等效关系, 建立了复合材料在不同加载条件(应变和温度)下的电阻变化的数学模 型, 并对实验结果和传感机理进行了讨论。研究结果可为应变传感器在不同温度条件下的进一步应用 提供参考。
