A smart window demonstrating dual chromic response properties based on engineered ionene/PNIPAM hybrid material that can adaptively control solar visible light transmittance in response to multiple stimuli is successfully engineered. This new blend generates unique reversible optical states which are passively triggered by environmental temperature and actively induced by external potential or simultaneously by both. Additionally, it shows tunability in terms of its electrochemical and optical properties, switching kinetics and coloration efficiency and achieves a nearly absolute zero-transmissive state. With the material’s excellent solubility and film forming ability, the smart device can be fabricated with much flexibility and ease. Lastly, this device has an all-in-one layer configuration creating a more compact and simplified design. Having all these remarkable properties, the design of highly efficient and more robust facades in buildings for energy saving is possible. |
