Electrosynthesis And Characterizations Of Some Poly(dyes)

The electrochemical polymerization and characterization studies were made forrnmonomers: malachite green, neutral red, aniline, and methylene blue using GC workingrnelectrode with respect to Ag wire reference electrode. The electrochemical properties ofrntheir corresponding polymers were also studied in monomer free solution using cyclicrnvoltammetry.rnCopolymer films were electropolymerized from malachite green and neutral red, andrnaniline and neutral red where neutral red plays a role of electrocatalysis. In addition, PBrnfilm was also deposited potentiostatically from 2mM K3[Fe(CN)6] and 2mM FeCl3rnsolution on to GC/Polymer modified electrode at a potential of +0.4 V for 60 s.rnGC/Polymer/PB modified electrodes were also characterized using cyclic voltammetryrnwhere the presence of PB film together with GC/Polymer modified electrode enhancesrnthe peak currents of the GC/Polymer modified electrode indicating PB film also plays arnrole of electrocatalysis.rnKey words: Electrosynthesis, poly(neutral red), poly(malachite green), poly(aniline),rnpoly(methylene blue), and Prussian blue.
