摘要

在这项工作中，我们证明了通过在有机溶剂中将石墨和聚四氟乙烯分散体喷洒在由天然和合成聚合物制成的纤维材料上，获得弹性导电复合材料的可能性。我们观察到，在 15-30% 的变形范围内，由于细丝的伸长和弹性收缩，所获得的纤维导电复合材料的电阻以及变形和应变敏感性参数发生了许多倍的变化。用基于针织物的导电复合材料制造的应变传感器实验室原型在循环变形条件下进行了测试，其电阻滞后极小（小于 4%）。

Effect of Air Temperature and Humidity on Electromechanical Properties of Elastic Graphite-Based Fiber Composites

In this work, we demonstrate the possibility of obtaining elastic electrically conductive composites by aerosol application of graphite and polytetrafluoroethylene dispersions in an organic solvent on fiber materials made of natural and synthetic polymers. We observe a manyfold change of electrical resistance, as well as deformation and strain sensitivity parameters of the obtained fiber electrically conductive composites due to elongation and elastic contraction of filaments in the deformation range of 15–30 %. Laboratory prototypes of strain sensors manufactured from electrically conductive composites based on a knit fabric with a minimal electrical resistance hysteresis (less than 4 %) were tested under cyclic deformation.
