The effects of plasma treatment on the strain sensing performance for the flexible conductive fibers

Ltd. All right reserved. In this paper, the preparation process and strain sensing performance of PPy-XLA fibers have been studied. However, the surface of XLA fiber is very smooth. Therefore, before the traditional chemical vapor deposition process, special treatment should be handled on the substrate fibers. Plasma treatment can change the roughness of the fiber surface, in order that PPy can be attached to the surface easily and increase the contact strength between PPy and substrate fiber. In this paper, the mechanical property and sensing performance of PPy-XLA fibers under different plasma time (5, 15 min) were compared. The experimental results show that plasma treatment had little influence on the mechanical property, but obviously affected the strain sensing performance.
