摘要

Electrochemical polymerization of aniline (ANI) was performed in aqueous 0.5 M H2SO4 using pulse potentiostatic method (PPSM). The polymeric films were deposited under different tuneable pulse parameters in PPSM like pulse number (Pn), pulse width (Pw) and variations of aniline concentrations. Cyclic voltammetry was used for evaluating the characteristics of the deposited polymeric films. A suitable equation relating the growth of the deposited films and the pulse parameters in PPSM was deduced as: growth = k[ANI]PnPw where k is growth rate constant and k value was evaluated through growth function. Various surface parameters were evaluated. The surface excess and thickness of the film showed increasing trend with increasing [ANI] and Pn. The polymer was also characterized in various acidity conditions. The elcectroactivity of the film was found to be retained in highly acidic solution and showed decreasing activity with increasing pH.
