Abstract
In this work, polypyrrole coated onto zinc surface anode electrode was successfully prepared via cyclic voltammetry deposition. The different PPy thickness layer on zinc electrode is controlled by the different numbers of deposited cycles at 3, 5, 7 and 10 cycles. The surface morphology development of polypyrrole nano/micro structure covering on zinc surface was examined by Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy. The electrochemical activity of polypyrrole coated zinc electrode is characterized by linear polarization, cyclic voltammetry and galvanic static charge-discharge, indicating that the anti-corrosion PPy surface covering on Zn electrode can yield the highest value of corrosion inhibition efficiency of 67% and serve as high redox layer to improve the charge performance.
