Question

what is the electrochemical and physicochemical behavior of polyaniline

Answer 1

Polyaniline (PANI) is a suitable compound for electrocatalysis, and can be combined with metal nanoparticles to fabricate high-performance electrodes for electrochemical energy conversion and storage. However, its intrinsic properties appear to be dependent on the synthesis conditions so that from the majority of the reports, it is quite difficult to establish an overall performance trend.

The amount of the oxidizing agent during the polymerization of PANI influences the amount of radical cations and thus the polymerization yield; however, an excess can lead to excessive oxidation of PANI, while a deficit may be insufficient to obtain the polymer.
