The anodically coloring material and the cathodically coloring material of the device are Prussian blue (PB) and poly (3, 4-ethylenedioxythiophene) (PEDOT) thin films, respectively. From the view of the structure, a laminated electrochromic glazing demands solid polymer electrolyte with both excellent sealing and ionic conductivity properties. The ionic conductivities of the CSIC-PVB films vary in the order of 10 ¡V3 down to 10 ¡V6 ?S/cm, whereas the adhesion strengths of these ion conducting PVB interlayers change from 3 to 11?N/mm 2 . The ionic conductivity and the adhesion of the CSIC-PVB films are proportional to the amount of ionic segments incorporated into the polymer backbone. This PB/CSIC-PVB/PEDOT laminated ECD has an optimal absorbance change at 620?nm. The ECD provides a 39.8% transmittance change (£GT) at the potential range between 1.0 V and ? 1.1?V (PEDOT vs. PB), with a bleaching time of 1.2?s and a darkening time of 1.5?s. And the coloration efficiency at 620?nm of the device is calculated to be 270.8?cm 2 /C. ? 2017 Elsevier B.V. |
