Polypyrrole-coated conductive fabrics as a candidate for strain sensors

The fabrication of PPy-coated conductive fabric by the method of vapor phase polymerization, and the investigation on its strain sensing properties were reported. The conductive fabrics were prepared by covering a non-conductive substrate with a layer of PPy conductive film which was formed by vapor phase polymerization. The vapor phase polymerization of PPy proceeded on the surface on the fabrics, under vacuum condition and at different temperature instantly. It was found that the conductive polymer-coated fabrics based on the PPy prepared by the method of vapor phase polymerization was a promising flexible strain sensor with very high sensitivity.
