Polypyrrole (PPy) film was fabricated on platinum substrate by a facile unipolar pulse electro-polymerization (UPEP) method. Mechanism for the formation of highly stable PPy film was proposed based on the chronoamperogram obtained during the polymerization process. Structure, surface morphology and hydrophilic property of the PPy film prepared using either UPEP method or potentiostatic method (PM)...
A novel unipolar pulse electro-polymerization (UPEP) method was used to prepare nanorod polyaniline (PANI) films on platinum substrates from aqueous solution containing 0.2molL −1 of aniline and 0.5molL −1 of sulphuric acid. The unipolar pulse waveform consisted of an applied anodic potential during the on-period and an open-circuit potential (zero current) during the off-period. The...
