Electrochemistry of conductive polymers. 30. nanoscale measurements of doping distributions and current-voltage characteristics of electrochemically deposited polypyrrole films

Article Abstract:

Spatial variations in electronic structures and evolutions of band structures of polypyrrole (PPy) are studied using an atomic force microscope with a conducting tip, a so-called current-sensing atomic force microscope (CS-AFM). It is concluded that the technique is useful in studying relations between electrical properties and preparation conditions of conducting polymers and also finding optimum conditions for specific purposes.

Hybrid materials polypyrrole/PW12O40(super 3-). 2. Physical, spectroscopic and electrochemical characterization

Article Abstract:

Physical, spectroscopic and electrochemical information on the potentiostatically synthesized hybrid material polypyrrole was obtained by means of electron microscopy, UV-vis spectroscopy, in situ UV-vis absorption-reflection spectroelectrochemistry, FTIR spectroscopy, EDX and cyclic voltammetry. The films before and after electrodissolution of the soluble fraction show similar flat morphology.
