Redox State Of Polyaniline Nanodot And Its Coulomb Staircase Effect, Jian-Zhang Zhou, Shao-Huang Weng, Zhong-Hua Lin
Journal of Electrochemistry
Polyaniline nanodot array had been fabricated in AAO template with potentiostatic method and the I~V characteristics of nanodots with different redox states were measured by conducting atomic force microscope (C-AFM) in atmosphere at room temperature. We found that only nanodots in partial oxidation state exhibit coulomb staircase in the I~V curves,while those in the full oxidation state and reduced state do not. The above phenomena were discussed preliminarily.
