Effect of long-term mechanical cycling and laser surface treatment on piezoresistive properties of SEBS-CNTs composites

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...
