Abstract
Thermal management smart windows can regulate indoor temperature by adjusting the intensity or spectral distribution of incoming solar radiation. This functionality helps reduce the energy demand of heating, ventilation, and air-conditioning (HVAC) systems, thereby contributing to energy conservation, emission reduction, and the achievement of carbon neutrality. Thermochromic hydrogels, with their intrinsic temperature responsiveness, broadband optical modulation capability, facile tunability, and low cost, have become as ideal thermochromic materials for thermal management smart windows. This review focuses on thermochromic hydrogels for thermal management smart windows, and introduces the research progress of intrinsic thermochromic hydrogels and their thermal management smart windows from the perspectives of chemical modification strategies and physical modification strategies. Then, the research progress of composite thermochromic hydrogels and their applications in thermal management smart windows is systematically reviewed, with particular emphasis on the incorporation of photothermal conversion fillers and thermochromic components. Moreover, current challenges and potential improvement strategies of thermochromic hydrogels for thermal management smart windows are identified and discussed. The aim of this review is to systematically summarize the optimization strategies for thermochromic hydrogels in thermal management smart windows and to provide guidance for future in-depth research, thereby promoting the advancement and application of thermochromic hydrogels for smart windows.
熱管理智能窗能夠通過調(diào)節(jié)入射太陽輻射的強度或波長以調(diào)控室內(nèi)溫度，這有助于降低暖通空調(diào)系統(tǒng)能耗，有助于節(jié)能減排與“雙碳”目標達成。熱致變色水凝膠因具備本征溫度響應(yīng)、寬光譜調(diào)控、易優(yōu)化改性及價格低廉等優(yōu)勢，成為該類智能窗的理想熱致變色材料。該綜述聚焦于熱管理智能窗用熱致變色水凝膠，從化學改性策略和物理改性策略的角度介紹了本征熱致變色水凝膠及其熱管理智能窗的研究進展，系統(tǒng)地回顧了熱致變色復(fù)合水凝膠及其在熱管理智能窗中的應(yīng)用研究進展，特別強調(diào)了光熱轉(zhuǎn)換填料和熱致變色填料的引入。此外，還指出了用于熱管理智能窗的熱致變色水凝膠當前面臨的挑戰(zhàn)以及潛在的改進策略，并進行了討論。該綜述旨在系統(tǒng)地歸納總結(jié)了熱致變色水凝膠在熱管理智能窗中的優(yōu)化策略，為未來深入研究提供指導(dǎo)，從而推動熱致變色水凝膠在智能窗領(lǐng)域的進步和應(yīng)用。
