Abstract
The electrochemical polymerization and characterization studies were made for monomers: malachite green, neutral red, aniline, and methylene blue using GC working electrode with respect to Ag wire reference electrode. The electrochemical properties of their corresponding polymers were also studied in monomer free solution using cyclic voltammetry. Copolymer films were electropolymerized from malachite green and neutral red, and aniline and neutral red where neutral red plays a role of electrocatalysis. In addition, PB film was also deposited potentiostatically from 2mM K3[Fe(CN)6] and 2mM FeCl3 solution on to GC/Polymer modified electrode at a potential of +0.4 V for 60 s. GC/Polymer/PB modified electrodes were also characterized using cyclic voltammetry where the presence of PB film together with GC/Polymer modified electrode enhances the peak currents of the GC/Polymer modified electrode indicating PB film also plays a role of electrocatalysis.
