Abstract: Structural characteristics of polypyrrole (PPy)-coated polycaprolactam (PA6) fiber composites prepared by chemical vapor deposition in the presence of ferric chloride as the oxidizing agent were investigated. A multi-layered coating structure has been observed by TEM, where a compact and denser layer exists, between the PPy and PA6 fibers with two diffused layers on each side of the denser layer. The experimental results show that there is no chemical interaction between PPy and PA6 in the PPy-coated PA6 fibers. However, there is a stronger interaction between PPy and PA6 molecules in the interphase of PPy-coated PA6 fiber after heat-treatment at elevated temperature. The surface morphology of PPy-coated PA6 fibers changed with the application of different processing treatments, e.g. swelling and heat-treatment.
