同步测量导电复合材料电阻-粘弹响应的柔性电极设计

Flexible electrodes for simultaneous measurement of resistance and viscoelastic responses of conductive polymer composites

设计并构建包括导电胶带电极和铜丝电极在内的两种柔性电极,用于对聚合物导电复合材料的电阻和粘弹响应进行同步测定;同时,提出一种基于电测量的方法来评估压敏导电胶带的固化过程。实验结果显示,在加热-冷却循环以及聚合物熔点之上的退火等老化过程的作用下,导电胶带的自粘特性可以有效提高电极和样品表面的粘结强度。铜丝电极能在适应样品变形的同时提供可靠的电接触,更适用于电阻-粘弹响应的同步测量。

Two flexible electrode includes a conductive tape electrode and a brass wire electrode have been designed and developed for simultaneous measurement of resistance and viscoelastic responses of conductive polymer composites. Additionally,an electrical measurement-based method has been proposed for evaluating the curing processes of pressure sensitive conductive tapes. The Results indicate that,during some aging processes such as heating-cooling cycles or annealing at a temperature above the melting point of polymer matrix,the self-affixing effect of the conductive tape has provided a reliable contact between the electrodes and the sample surfaces by improving the bonding strength. Under these aging processes, the brass wire electrodes are proved to be suitable for simultaneous measurement of resistance and viscoelastic responses.
