As polypyrrole (Ppy) has unique doping and dedoping characteristics, the new nano-materials redoped and doped Ppy composites with special anti-corrosive functional groups were successfully prepared by direct oxidation in the stainless steel(SS) surface respectively. The microcomic structure, morphology and anti-corrosive performance of the redoped Ppy were characterized by Cyclic voltammetry(CV), scanning electron microscopy(SEM), Polarization curves(PC) and electrochemical impedance spectroscopy (EIS), and compared with a doped and undoped Ppy, and their anti-corrosion mechanism were investigated theoretically. The results show that, the stainless steel surface covered with redoped and doped Ppy composites had good anti-corrosive performance, the redoped Ppy composites had the best. The corrosion potential of the redoped Ppy composite was increased by about 0.989V and the corrosion current is reduced by about 2 orders of magnitude to pure Ppy. The dense membrane structure of the redoped Ppy significantly increased, membrane defects significantly reduced, the best corrosion resistance, so it has a better anti-corrosion behavior..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
