Naturally derived nanocellulose (NC) is a renewable, biodegradable nanomaterial with high strength, low density, high surface area, and tunable surface chemistry, which allows its interaction with other polymers and nanomaterials in a controlled manner. In recent years, NC aerogel has gathered a lot of attention due to environmental concerns. This review presents recent developments of NC-based aerogels and their controlled interactions with other polymers and nanomaterials for thermal applications that include electronic devices, the apparel industry, superinsulating materials, and flame-retardant smart building materials. After going through the distinctive properties of NC aerogels, they are orderly categorized and discussed as thermally insulated, thermally conductive, and flame-retardant materials.
天然衍生的纳米纤维素（NC）是一种可再生、可生物降解的纳米材料，具有高强度、低密度、高比表面积和可调节的表面化学性质，这使得它能够以可控的方式与其他聚合物和纳米材料相互作用。近年来，由于环境问题，NC气凝胶受到了广泛关注。本文综述了基于NC的气凝胶的最新进展，以及它们与其他聚合物和纳米材料在热应用方面的可控相互作用，这些热应用包括电子设备、服装行业、超级绝缘材料和阻燃智能建筑材料。在介绍了NC气凝胶的独特性能之后，它们被有序地分类并作为隔热材料、导热材料和阻燃材料进行了讨论。
