  • Descrição: Natural polymers are particularly interesting due to their richness in nature, very low cost and principally biodegradation properties. For these reasons different solid polymeric electrolytes (SPE) have been obtained using cellulose derivatives, starch, chitosan and rubber. This work presents the results of gelatin-based electrolyte, which were characterized by impedance spectroscopy, X-ray diffraction and thermal analysis. The ionic conductivity results obtained for these SPEs were 1. 5 x 10(-5) S/cm and 4.9 x 10(-4) S/cm at room temperature and 80 degrees C, respectively. Temperature-dependence ionic conductivity measurements were taken to analyze the mechanism of ionic conduction in polymer electrolytes. Thermal analysis using differential scanning calorimetry (DSC) was performed in order to observe the change in transition temperature caused by the addition of salt to the electrolyte. Good conductivity results combined with transparency and good adhesion to the electrodes have shown that gelatin-based SPEs are very promising materials to be used as solid electrolytes in electrochromic devices
