Electrochemical atomic force microscopy: In situ monitoring of electrochemical processes

The in-situ electrodeposition of polyaniline (PANI), one of the most attractive conducting polymers (CP), has been\udmonitored performing electrochemical atomic force microscopy (EC-AFM) experiments. The electropolymerization of PANI on\uda Pt working electrode has been observed performing cyclic voltammetry experiments and controlling the evolution of current\udflowing through the electrode surface, together with a standard AFM image. The working principle and the potentialities of this\udemerging technique are briefly reviewed and factors limiting the studying of the in-situ electrosynthesis of organic compounds\uddiscussed
