摘　　要：自然界中大多数材料具有正热膨胀系数,随温度升高而膨胀。过大的热膨胀会影响结构的热稳定性,对精密部件的功能性和安全性造成不良影响。超材料依靠精心设计的微结构,能够实现天然材料无法达到的新奇特性,为实现负热膨胀、近零热膨胀和可编程热膨胀提供了良好的平台。本文从这三方面综述了可编程热控超材料的研究进展,并展望了该类超材料的应用前景和发展方向,可为变温环境下的应用提供参考,如观测卫星、相控阵天线、燃料电池等。Most materials in nature have positive coefficients of thermal expansion,expanding as temperature increases.Excessive thermal expansion can compromise the thermal stability of structures and adversely affect the functionality and safety of precision components.Metamaterials rely on ingeniously designed microstructures to achieve exotic properties that can not exist in natural materials,providing a good platform for realizing negative thermal expansion,near-zero thermal expansion and programmable thermal expansion.This paper reviews the recent advancements in programmable thermal control metamaterials from these three perspectives,and provides an outlook on their application prospects and future research directions.This review serves as a reference for applications in variable temperature environments,such as observation satellites,phased array antennas,and fuel cells.
