Cutting-Edge Graphene/Amorphous Boron Nitride Aerogel: A Breakthrough in Thermal Superinsulation
Scientists have developed a chemically bonded multi-nanolayer design and synthesis of a graphene/amorphous boron nitride aerogel (a-BNGA) to improve the thermal and mechanical properties concurrently. The a-BNGA exhibits ultralow density, ultrahigh flexibility, and outstanding thermal stability. It has record-low thermal conductivity in a vacuum among freestanding solid materials, making it a promising material for thermal superinsulation in extreme conditions such as lunar and Mars bases, satellites, and spacecraft. This research opens up opportunities for inorganic aerogels to have other unique functions.
