Study on the electrochemical degradation of poly-N-acetylaniline by electro-hydrolysis and electro-chlorination

Poly-N-acetylaniline (PNAANI) film, an analogous polymer of polyaniline, was electrodeposited on a glassy carbon (GC) electrode by an electro-dynamic scan method. Cyclic voltammetry was used to characterize the electrochemical response. The cyclic voltammograms of PNAANI films after its electro-hydrolysis and electro-chlorination were interpreted. The electrode processes are discussed and the electrochemical degradation mechanism of PNAANI film proposed based on the experimental results.
