Description
Summary:Polypyrrole (PPy) is one of the most common conducting polymers in research and investigation due to its good stability, high conductivity, ease of preparation, and non-toxicity. It has wide applications in the field of chemical sensors, electromagnetic interference shielding devices, electrochromic devices and batteries. Furthermore, it was found that when PPy coating was deposited on some commercial fabrics, the conductivity changes to a large extent, PPy can detect large strain deformation, however only few investigations on the strain sensitivity of PPy-based composites can be found. In this paper, the fabrication of PPy-coated conductive fabric by the method of vapor phase polymerization, and the investigation on its strain sensing properties are reported.
