The electrosynthesis of nanostructured polypyrrole (PPy) on copper interdigital electrodes (Cu‐IDEs) surfaces was performed by anodic oxidation of pyrrole in the presence of oxalic acid in aqueous solution (passivation technique) by potentiostatic method. Some divalent transition metal ions (Fe(II), Co(II), Ni(II), Cu(II), Zn(II)) as catalyst can be used to polymers growth on/between spacing between...
Nanostructured conductive polypyrrole has been prepared electrochemically on the surfaces of Cu/Au interdigital electrodes in the presence of Fe(II) as catalyst and ClO4− as anion dopant by using constant potential amperometry and cyclic voltammetry. The morphology of the conducting films was examined by field emission scanning electron microscopy, indicating a dependence from the processing technique...
