Description :
In this paper we report the synthesis and electrochemical study of ternary composites of conducting polymer polypyrrole (PPY) and CNT - MnO 2 so as to use them in device application. Ternary composites of PPY/CNT/MnO 2 have been synthesized by in - situ chemical polymerization. Electrospun nanofibers of ternary composite were f abricated by using poly vinylidene fluoride (PVDF) as carrier polymer. Analytical techniques such as SEM, FTIR, and XRD are used to characterize the synthesized ternary composites. The ternary composite showed good interaction based on the shift to longer wavelengths in the electronic transition, indicating the interaction between PPY and CNT - MnO 2 as observed in their FTIR spectra of powder as well as fibers. Crystallinity of MnO 2 in ternary composite was confirmed from XRD results. The SEM images of synthe sized ternary composites reveal dispersion of polymer over CNT and the SEM images of fiber indicates the diameter of fibers in the range of 100 - 300nm. Electrochemical study was done by cylic voltamettry(CV), Galvanostatic Charge - Discharge (GCD) and Electr ochemical Impedance Spectroscopy (EIS).
