摘要
电致变色智能窗可以控制进入建筑的光照和热量,是降低建筑能耗的有效手段。然而,目前大多数电致变色智能窗在可见光与近红外辐射的智能调控方面存在不足。本文报道了一种通过简单经济的脉冲电化学沉积法制备的非晶态多孔WO_(3)薄膜,非晶多孔薄膜不仅有利于离子传输,还为Li+吸附提供了大的表面积,从而在近红外范围内实现了表面等离子体共振吸收,展现出对可见光与近红外辐射的选择性调控能力,以及快速的响应时间、超高的着色效率和优异的循环稳定性。基于该非晶态WO_(3)薄膜的电致变色智能窗,在施加不同电压时可选择性地透过不同波段的光,展现出了强大的光、热调控能力,有望降低建筑能耗。该研究拓宽了电致变色智能窗的应用领域,可推动绿色建筑的发展,为“双碳”政策的实现做出积极的贡献。
Electrochromic smart windows,capable of controlling light and heat entering buildings,are an effective means to reduce building energy consumption.However,most current electrochromic smart windows lack sufficient capability for intelligent regulation of both visible light and near-infrared radiation.This paper reports an amorphous porous WO_(3) film prepared by a simple and economical pulsed electrodeposition method.The amorphous porous film not only facilitates ion transport but also provides a large surface area for Li+adsorption,enabling surface plasmon resonance absorption in the near-infrared region.This results in selective modulation capability for visible and near-infrared radiation,along with fast response times,ultra-high coloration efficiency,and excellent cycling stability.The electrochromic smart window based on this amorphous WO_(3) film can selectively transmit light of different bands under applied voltages,demonstrating powerful light and heat regulation capabilities,promising for reducing building energy consumption.This research broadens the application field of electrochromic smart windows,can promote the development of green buildings,and make a positive contribution to achieving the"dual carbon"policy goals.
