Effect of Sodium Salicylate on Electropolymerization of Pyrrole on Zincated Steel
水杨酸钠对电镀锌钢板上电聚合吡咯的作用

The role of sodium salicylate in electropolymerization of pyrrole on zincated steel was studied by cyclic voltammetry. The results show that as supporting electrolyte, the sodium salicylate inhibits the zinc dissolution and favours the electropolymerization of pyrrole by passivating the substrate. Consequently, an uniform and compact polypyrrole film may be formed on zincated steel.
