Preparation and Characterization of Conducting Poly(ethylene terephthalate)/Polypyrrole Composite Fibers

The conducting poly(ethylene terephthalate) (PET)/polypyrrole (PPy) composite fibers were prepared by chemical polymerization of pyrrole in the presence of PET fibers using various oxidants. The most suitable medium from the points of the lowest electrical surface resistivity and the highest PPy content of composite fibers was observed to be aqueous hydrochloride acid solution with K2S2O8, and the pyrrole concentrations of 0.08 M and 0.04 M, respectively. Characterization of conducting composite fibers was performed by surface resistivity, density, and diameter measurements, FTIR, TGA, optical microscope, and SEM techniques.
