The ambition of human beings to create a comfortable environment for work and life in a sustainable way has triggered a great need for advanced thermal insulation materials in past decades. Aerogels and foams present great prospects as thermal insulators owing to their low density, good thermal insulation, mechanical robustness, and even high fire resistance. These merits make them suitable for many real-world applications, such as energy-saving building materials, thermally protective materials in aircrafts and battery, and warming fabrics. Despite great advances, to date there remains a lack of a comprehensive yet critical review on the thermal insulation materials. Herein, recent progresses in fire-safe thermal-insulating aerogels and foams are summarized, and pros/cons of three major categories of aerogels/foams (inorganic, organic and their hybrids) are discussed. Finally, key challenges associated with existing aerogels are discussed and some future opportunities are proposed. This review is expected to expedite the development of advanced aerogels and foams as fire-safe thermally insulating materials, and to help create a sustainable, safe, and energy-efficient society.
在过去几十年里，人类以可持续的方式为工作和生活创造舒适环境的雄心引发了对先进隔热材料的巨大需求。气凝胶和泡沫材料因其低密度、良好的隔热性能、机械强度高甚至耐火性强等特点，作为隔热材料展现出巨大的前景。这些优点使其适用于许多实际应用，如节能建筑材料、飞机和电池中的热防护材料以及保暖织物。尽管取得了巨大进展，但迄今为止，仍缺乏对隔热材料全面而关键的综述。在此，总结了防火隔热气凝胶和泡沫材料的最新进展，并讨论了三大类气凝胶/泡沫材料（无机、有机及其复合材料）的优缺点。最后，讨论了现有气凝胶面临的关键挑战，并提出了一些未来机遇。本综述有望加速先进气凝胶和泡沫材料作为防火隔热材料的发展，并有助于创建一个可持续、安全和节能的社会。
