The electrosynthesis of polypyrrole films was devised by consecutive potential steps. The time of each anodic and cathodic step, the number of consecutive steps, and the anodic potential of polarization influence the structure of the obtained polymer film, its adherence to the metal electrode and its electrochromic answer. Larger anodic polarization times (per step) give a polymer film formed by dendrites. Shorter anodic polarization times (per step) give smooth and adherent films. Darker colours were obtained when the number of polymerization potential steps increases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
