| Abstract:In order to prepare an electrochromic device by using gel electrolyte based on agar, electrolyte solution was prepared with
agar as matrix, lithium bis(trifluoromethanesulphonyl) imide (LiTFSI) as electrolyte salt, propylene carbonate (PC) as plasticizer and
deionized water as solvent after stirring and heating. Prussian blue (PB) film was prepared by electrodeposition, and assembled into an
electrochromic device. The prepared electrolyte solution was injected into the electrochromic device and transformed into gel electrolyte
after cooling. The electrochromic device based on agar gel electrolyte was obtained. Its electrochromic properties were studied. The
results show that the transmittance modulation of the electrochromic device reaches 39.9% at the wavelength of 580 nm. The coloration
and bleaching responses of the device are 16.2 s and 15.2 s respectively, which show that the electrochromic device exhibits fast switching
responses. |
