Polypyrrole(PPy) thin films were deposited on vapor grown carbon fibers(VGCF). Formation of PPy on VGCF was carried out by using an in-situ chemical polymerization of the monomer in presence of FeCl3 oxidant. An ultrasonic cavitational stream was used during polymerization of pyrrole, to enable the deposition of uniformly thin (ca.7nm) PPy films onto the surface of VGCF. The PPy/VGCF composite was characterized by FTIR spectroscopy. The surface morphology of the polymer films were characterized by using scanning electron microscopy (SEM) and scanning transmission emission microscopy (TEM).
