Abstract
The influence of organic dyes in polypyrrole (PPy) preparation has been significantly manifested in the change of its morphology and increase in conductivity. The addition of Acid Blue 25 (AB25) and Acid Blue 129 (AB129) during the electrosynthesis of pyrrole supports the modification of PPy morphology (forming fibers and smaller globular structures, respectively) and led to a switch in PPy electrochemical behavior as well as stability. PPy-AB25 exhibits higher electroactivity, capacitance, and diffusion–controlled capacitive contribution than PPy-AB129.
