Some galvanic couples were designed with PPy films to simulate possibly formed corrosion cells on PPy. Their effects on the corrosion of PPy were investigated using electrochemical methods and XPS analysis. The results indicate that the PPy redox state difference cell just occurs in the initial corrosion period and can not be sustained on PPy. The H + ion and electrolyte concentration difference...
The effects of continuous cathodic and anodic polarisation on the corrosion of polypyrrole (PPy) films were investigated in neutral 0.1M NaCl with various electrochemical methods and spectroscopic analyses. With continuous cathodic polarisation, the PPy film nearly maintains the conjugated structure of PPy chains, but loses its electroactivity slightly. With increases in anodic polarisation potential...
