Aerogel materials serve a vital role as protective materials needed for many fields, including as electromagnetic interference shielding material for 5G technology, thermally insulating material in high-rise buildings and infrared stealth material for military applications. Current protective materials, however, often lose their protective functions under harsh conditions such as extreme temperatures, rendering them ineffective. Other protective materials lose their elasticity, leading to similar performance issues. Now, new aerogel materials that can maintain their functionality and superelasticity under extreme temperatures have been developed.
