The improvement of free-radical scavenging capacity of the phosphate medium electrosynthesized polyaniline
چکیده انگلیسی

The oxidative polymerization of aniline on composite 2B pencil graphite was accomplished in phosphoric acid (H3PO4) containing 0.06 M calcium phosphate (Ca3(PO4)2). The shifting of three pairs of redox peaks by 250 mV to the negative direction has increased antioxidant capacity of polyaniline (PAni). This was realised through reaction with 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical in methanol. The phosphate medium prepared PAni was a strong reducing agent and radical scavenger. Additionally, it was twice more effective than the one prepared in chloride medium.
