報內容摘要:

Electrochromic materials are able to change their bandgap by doping and de-doping chemical reactions. As the result, the electrochromic device could modulate the optical properties, such as transmittance, reflectance, absorptance, or emittance, under the action of an electrical voltage or current. Electrochromic film utilizes flexible light-weight plastic substrate, which could be directly integrated onto the glass, transferring the standard glass to smart glass. We use semiconducting polymer as the electrochromic layer and solid-state electrolyte. The optical properties of the semiconducting polymer can be easily adjusted by varying the molecular structure, which offers a choice of multicolors. The solid-state electrolyte avoids the problem of leakage commonly associated with liquid electrolytes, and provides high ion-conductivity to realize fast switching speed. All the functional materials are solution processable, which high throughput, low cost, scalable roll-to-roll manufacturing process can be employed to fabricate the electrochromic film, reducing the cost significantly. The application of electrochromic technology includes auto-dimming mirrors, displays, smart window, and sunroof. Among those, smart-window is of great importance due to its potential to reduce energy consumption.
