Abstract

Electropolymerization is a useful method to modify electrode for improving selectivity, sensitivity and strong adherence to electrode surface. In this paper, we prepared polydopamine (PDA), poly-para-aminobenzoic acid (PABA) and PDA/PABA composite membrane on a glassy carbon electrode (GCE) using cyclic voltammetry. The composite membrane was electrochemically degraded to form a porous polydopamine membrane (PPM) on the GCE. The porosity of the PPM was examined using anionic redox couple of ferricyanide/ferrocyanide. PPM modified electrodes were able to give better voltammetric responses for dopamine (DA) oxidation than the single PDA and PABA modified ones.
