Xerogel samples with n ≥ 1 are thermally stable up to 235 ºC. A minor proportion of PCL crystallites occur in some dilute-to-concentrated samples. At n ≤ 4 a crystalline PCL(530)/siloxane-KCF3SO3 complex with unknown stoichiometry emerges. At n ≤ 2 this complex coexists with pure salt. At temperatures higher than 40 ºC the composition which exhibits the highest ionic conductivity is n = 21. “Free” anions, weakly coordinated CF3SO3- ions, contact ion pairs and several higher ionic aggregates emerge in all the samples. The K+ ions bond to the oxygen atoms of the carbonyl groups of the urethane and ester groups, of the PCL (530) ether chain and of the triflate ions at all salt concentrations. The ormolytes were successfully used in the production of prototype electrochromic devices (ECDs) that exhibit low switching time and good open circuit memory.. The ECD incorporating the ormolyte with n = 21 displays an average transmittance in the visible region of ca. 55 % in the colored state and 76 % in the bleached state.Fundação para a Ciência e Tecnologia (FCT)ElsevierUniversidade do MinhoFernandes, M.Rodrigues, L.
