Growth of Polypyrrole Film by Irradiation

초록

Polypyrrole(PPy) is one of the most stables conducting polymers due to its high themostability and life stability. In constract with well-known polymerization method, we have synthesized PPy nanofilms using vapor-phase oxidative polymerization process in a vacuum chamber under various irradiation. Resistance change of the PPy nanofilms measured by a Keithley 2400 multi-meter, are characterized by atomic force microscopy (AFM), Raman spectroscopy, Fourier-Transform infrared spectroscopy (Ft-IR) and field emission scanning electron microscopy (FE-SEM). Possible mechanism is proposed for the formation of the PPy nanostructure during the vapor-phase oxidative polymerization under irradiation of various wavelength.
