Аннотация
The electrochromic properties of polypyrrole (PPy) synthesized with two
different dyes, Remazol Black B (RB) and Dianix Red (DR), have been
investigated concerning the influence of dye molecules on polymer
structure ordering and electrochromic characteristics. The polymers have
been electrochemically prepared. Structural characterization by X-ray
diffraction (XRD) and Raman spectroscopy has shown the improvement of
PPy chain ordering by dye molecules, which provides an easy mass
transport at the interface, a better electronic charge transfer in the
bulk, and resulting better electrochromic properties. (c) 2006 Elsevier
