The piezoresistive behaviour of SEBS-CNTs nanocomposites was investigated to evaluate their.

potential applications as strain sensors. Composites containing from 3%wt. to 7%wt. of CNTs were processed by injection moulding in order to evaluate the percolation threshold. The piezoresistive response under flexural strain of nanocomposites with a CNTs content above the percolation threshold was then studied. The nanocomposites showing the most promising performance were tested under cyclic conditions. Conductive tracks were then processed on nanocomposites surfaces (with 3 and 4% of CNTs) by means of a laser treatment. Samples with optimized laser tracks were then submitted to 1000 stretching/releasing cycles, showing improved piezoresistive performance.

研究了SEBS-CNTs纳米复合材料的压阻行为。

作为应变传感器的潜在应用。含3％wt的复合材料。至7％重量 为了评估渗滤阈值，通过注射成型处理了5批CNT。然后研究了CNTs含量高于渗滤阈值的纳米复合材料在弯曲应变下的压阻响应。在循环条件下测试了表现出最有希望的性能的纳米复合材料。然后通过激光处理在纳米复合材料表面（含3％和4％的CNT）上处理导电迹线。然后将具有优化激光轨迹的样品进行1000次拉伸/释放循环，显示出改进的压阻性能。
