The study focused on polypyrrole (PPy) prepared with organic dyes for its interesting morphology and electronic properties. It described the preparation of electropolymerized PPy/safranin-O film and found that incorporating safranin-O significantly enhanced the areal capacitance of PPy.
Polypyrrole (PPy) prepared in the presence of organic dyes has been recently studied due to its interesting morphology and electronic properties. This present work describes the facile preparation of electropolymerized PPy/safranin-O film with varying safranin-O concentrations through cyclic voltammetry. Raman spectra of the films confirm the presence of PPy and safranin-O while UV-Vis spectra of the films suggest an interaction between safranin-O and PPy. In the presence of added safranin-O, a cauliflower-like morphological formation on the film's surface is obtained. The areal capacitance of PPy is significantly enhanced by the incorporation of safranin-O with values from 22.89 mF/cm(2) to a higher capacitance value of 277.8 mF/cm(2) at 10 mV/s scan rate. The PPy/safranin-O films showed better cycling stability over 1000 cycles than a pristine PPy film.
