Polymer electrolytes for electrochromic devices through solvent casting and sol-gel routes
Abstract
<p>Ionically conductive membranes of gelatin and d-PCL(530)/siloxane doped with cyano-based ionic liquids (ILs) were prepared through solvent casting and sol-gel methods, respectively. The membranes were characterized in terms of ionic conductivity, thermal behavior, morphology, and structure. All samples, except the d-PCL(530)/siloxane matrix, exhibited a predominantly amorphous morphology. The samples prepared through solvent casting and sol-gel displayed a minimum thermal stability of 170 and 230 °C, respectively. The ionic conductivity varied according with the type, quantity, and length of the alkyl chain of the cation of the ILs. The sample with the highest ionic conductivity was gelatin<sub>0.5</sub>[C<sub>2</sub>mim][N(CN)<sub>2</sub>] with 2.40×10<sup>−3</sup> S cm<sup>−1</sup> at 25 °C and 1.68×10<sup>−2</sup> S cm<sup>−1</sup> at 95 °C. The good results of ionic conductivity encouraged the assembly and characterization of prototypes of electrochromic devices (ECDs). The best results were obtained with glass/ITO/WO<sub>3</sub>/gelatin<sub>1</sub>[C<sub>2</sub>mim][SCN]/CeO<sub>2</sub>-TiO<sub>2</sub>/ITO/glass configuration that showed a fast color switching time (~15 s) and a good open circuit memory (~4 h). The ECD changed its color from pale blue to transparent, and its charge density decreased from −17.53 to −2.71 mC cm<sup>−2</sup> during 640 color/bleaching cycles.</p>
