Gelatin_nZn(CF₃SO₃)₂ Polymer Electrolytes for Electrochromic Devices

Abstract

The present work is focused on gelatin-based electrolytes doped with a range of concentration of zinc triflate (Zn-(CF 3 SO 3 ) 2 ). The transparent-thin-film samples have been represented by the notation Gelatin n Zn(CF 3 SO 3 ) 2 , where n represents the zinc triflate salt concentration in the electrolyte membranes from 0.00 wt% to 10.93 wt% . The samples have been characterized by conductivity measurements, thermal analysis, cyclic voltammetry, X-ray diffraction (XRD), polarized optical microscopy (POM) and scanning electron microscopy (SEM). The gelatin-based electrolytes were also tested as ionic conductors in electrochromic devices with the glass/ITO/WO 3 /gelatin-based electrolyte/CeO 2 -TiO 2 /ITO/glass configuration.

Electrochromic device with Prussian blue and HPC-based electrolyte

“…These color changes from transparent to blue are shown on pictures of measured ECD (Fig. 4 insets) glass/SnO2/PEDOT/electrolyte/PB/SnO2/glass configuration [8], which resemble the ECD with WO3 and gelatin-based electrolyte [30,31]. However, they are similar to the voltammograms obtained for ECD with poly(vinyl butyrate) (PVB) electrolyte [32].…”

Electrochromic Windows with PVB Electrolytes

“…Different solid and gel electrolytes including polymeric ones are investigated [8,9]. Also, gel polymer electrolytes based on natural macromolecules are prepared and characterized [10,11].…”

Pectin-based Polymer Electrolytes with Ir(III) Complexes

“…One of the most promising approaches to overcome environmental problems is the use of biodegradable polymers useful for various applications in medical, pharmaceutical, agriculture, drug release, and electrochemical devices [4][5][6].…”
