One-dimensional growth of polyaniline (PANI) was conducted on carbon cloth through a pulse potentiostatic method Hydrolysis of PANI was depressed, and the generated PANI film (PPM) displayed improved electroactivities The specific capacitance of PPM was increased by 39% when compared to that of PANI film made by the conventional potentiostatic method (PM) The influences of the upper limit potential of the pulse potentiometry and the acidity of the polymerization solution on surface morphologies, electroactivities and conformation oldie PANI films were studied by SEM, cyclic voltammetry, chronopotentiometry and UV-Vis spectrometry (C) 2010 Elsevier Ltd.
