Abstract

The formation of polypyrrole (PPy) layers by electrochemical polymerisation of pyrrole (Py) on paraffin impregnated graphite electrode (PIGE) was studied. Electrochemical oxidation of Py was studied by means of cyclic voltammetry (CV) and the morphology of the deposited layers was investigated with scanning electron microscope (SEM). The structure and quality of PPy layers on PIGE depends on monomer concentration, pH value, stirring intensity and scan rate during the polymerisation process.
