Abstract
An all-solid-state electrochromic device with a mixture of UV curable resin and liquid electrolytes as new electrolyte, tungsten trioxide as an electrochromic material, and LiClO4 as an electron donor was reported. PMMA was simply mixed with a PC solution to improve the electrolyte stability. Capillarity was used to make the device, and ultraviolet light was used to complete the packaging. The device is made of capillary phenomena and encapsulated by ultraviolet light. The composition, morphology, and transmittance of the films and the response time of the device were measured. A new type of electrolyte was prepared that greatly reduces the encapsulation time and solves the leakage problem by encapsulation. The final device has excellent optical memory, can complete the colouring fading cycle within 10 s, and has a transmittance between 10% and 90% at 800 nm and between 65% and 95% at 400 nm.
