Formation Mechanism of Polyaniline Nanostructures in PEG Solution

Nano structured polyaniline was intensively studied for its low price, fascinating tunable conductive properties by dope-dedope process. While the nanostructural formation mechanism still not clear. In this work, PANI nanostructures were obtained in acidity PEG solution, and the polymerization process was monitored by a pH instrument. Moreover, the morphology evolution was monitored, based on which a self-assemble mechanism was issued. The oxidation products of anilinium cations were consider as the seed template for the formation of nanostructures, and appropriate acidity is propitious to the formation of PANI nanostructures.
