面向实际应用的基于VO2的温度自适应辐射材料研究进展

Abstract The escalating challenges of global warming have created unprecedented demand for sustainable cooling solutions. Among these, vanadium dioxide (VO 2 )-based materials have emerged as promising candidates for energy-efficient thermal management. The reversible insulator-to-metal transition between monoclinic VO 2 (M1) and rutile VO 2 (R) phases at the phase transition temperature (T c ) triggers abrupt optical switching, enabling dynamic radiative regulation. However, their practical applications are hindered by a fixed Tc and limited spectral modulation capabilities. This review systematically outlines recent advancements in optimizing the thermochromic performance of VO 2 through elemental doping strategies and micro/nano-structural engineering. These enhanced VO 2 -based materials exhibit superior performance advantages in practical applications, including smart windows, spacecraft thermal management, and infrared stealth. Nevertheless, most studies focus on single-performance metrics while neglecting multidimensional challenges in real-world applications, such as environmental durability, scalable fabrication, and cost-effectiveness. This review critically analyzes current bottlenecks in the performance-stability-cost balance dilemma to guide the transition from laboratory breakthroughs towards sustainable, large-scale applications. Furthermore, interdisciplinary opportunities for VO 2 -based temperature-adaptive radiative materials are envisioned, given the unique response characteristics of VO 2 , further expanding their potential from adaptive building and space thermal control to sustainable personal thermal management, redefining their role in next-generation sustainable thermal management technologies.
