In this study, solid polymer electrolyte (SPE)
based on chitosan (Ch) was prepared with addition of poly(3,4-ethylenedioxythiophene):polystyrene
sulfonate (PEDOT:PSS), lithium trifluro methane sulfonate (LiTRIF), propylene carbonate (PC) by solvent casting
technique. The chitosan-based polymer electrolyte was characterized using electrochemical impedance spectroscopy (EIS). The ionic
conductivity value was calculated as 4.2 x 10-4 S/cm. The SPE having
good ionic conductivity was used to fabricate electrochromic device with
glass/ITO/WO3׀PEDOT:PSS-Ch-LiTRIF-PC׀ITO/glass whose
performance was evaluated via cyclic voltammetry, transmittance, repeating
chronoamperometry. The optical contrast of ECD was attained as 22% at 800 nm,
which resulting in coloration efficiency of 67 cm2/C. The ECD displays fast
response time for coloration (tc ) is 0.29 s. Upon reversal of
potential bleaching (tb ) forms within 3 s. The findings
demonstrated that this SPE electrolyte has promising candidate for use in
optoelectronic applications.
