摘要
Polyaniline films were successfully synthesized on zinc-electroplated steel sheets in sodium salicylate (1mol·dm-3) aqueous medium. This one-step aniline electropolymerization process has been studied in this paper using different electrochemical techniques. And scanning electron microscopy (SEM) showed that the polymer coatings rapidly formed by either galvanostatic or potentiostatic mode performed compact and uniform in morphology. Potentiodynamic polarization was used to test the anticorrosion properties of this polymer.
