A study of the interaction between 15 grades of alkaline sized paper and four conductive polymers was carried out to determine which polymer had the best potential for use as an electrochromic material in flexible packaging applications. Based on measurements of surface conductivity and cyclic voltammetry, it was determined that poly(3,4-ethylenedioxythiophene) (PEDOT) and polypyrrole (PPy) had the best properties. When the electrochromic properties of the two materials were compared it was concluded that PPy was the best candidate, despite potential processing difficulties related to the insolubility and infusibility of the polymer. Three possible solutions to the challenge of applying PPy were devised. The first attempted to produce a nano dispersion by milling PPy with a conductive dispersant. The second attempted to produce a nano dispersion directly by modifying the PPy synthesis conditions. The third attempted to produce a continuous film by in situ reaction of pyrrole monomer and oxidant on the substrate surface. The experimental results to date indicate that all three approaches have promise, but that difficulties remain in each case that must be solved before electrochromic inks based on conducting polymers can achieve commercial application.
