Evaluation of active materials designed for use in printable electrochromic polymer displays
Artikel i vetenskaplig tidskrift, 2006

In a step towards roll-to-roll prodn. of polymer-based electrochromic displays on flexible substrates, nine thiophene-based polymers and copolymers designed to increase the contrast of displays based on poly(3,4-ethylenedioxythiophene)/poly(styrene-sulfonic acid) have been synthesized and evaluated with respect to their absorbance (contrast), switch speed, and ability to switch reversibly in a water-based electrolyte. The results of the evaluation, including cyclic voltammetry and optically visible absorption, provide a basis for understanding what an aq. electrolyte electrochromic display requires in terms of oxidn. potential and material stability, and the effect of chem. structure on the reversibility and speed of switching.
