Research Progress and Applications of Passive and Dynamic Thermal Management Composite Fabrics

  • 摘要: 随着全球变暖和能源消耗加剧,开发零能耗热管理材料对节能减排至关重要。传统单一功能织物难以适应复杂多变的环境温度,本文综述了兼具辐射冷却与太阳能加热的双功能主动与动态热管理复合织物的最新进展。这类材料通过手动翻转、刺激响应等方式调控光谱,实现了对人体、特殊职业防护等的高效能耗管理,显著扩展了热舒适范围并降低对暖通空调系统的依赖。然而,其实际应用仍面临材料循环稳定性不足、测试标准不统一、制备工艺复杂且成本较高等挑战。未来需重点发展响应温度更贴近人体舒适区间、性能稳定可靠的材料体系,并建立与现有产业兼容的低成本规模化制备技术,以推动该领域从实验室走向实际应用。

     

    Abstract: With global warming and energy consumption intensifying, developing zero-energy thermal management materials is crucial for energy conservation. Conventional single-function fabrics struggle to adapt to complex and variable ambient temperatures. This review summarizes recent advances in dual-functional active and dynamic thermal management composite fabrics that combine radiative cooling and solar heating. By regulating their spectral properties through manual flipping or stimulus-responsive mechanisms, these materials enable efficient thermal management for the human body and specialized occupational protection. They significantly widen the thermal comfort range and reduce reliance on HVAC systems. However, practical applications still face challenges such as insufficient cycling stability, a lack of standardized testing protocols, complex fabrication processes, and high costs. Future efforts should focus on developing material systems with response temperatures closer to the human comfort zone and with stable, reliable performance. Establishing low-cost, scalable manufacturing technologies compatible with existing industries is also essential to advance this field from the laboratory to real-world applications.
