摘要

Ceramic aerogels (CAs) have emerged as a significant research frontier across various applications due to their lightweight, high porosity, and easily tunable structural characteristics. However, the intrinsic weak interactions among the constituent nanoparticles, coupled with the limited toughness of traditional CAs, make them susceptible to structural collapse or even catastrophic failure when exposed to complex mechanical external forces. Unlike 0D building units, 1D ceramic nanofibers (CNFs) possess a high aspect ratio and exceptional flexibility simultaneously, which are desirable building blocks for elastic CAs. This review presents the recent progress in electrospun ceramic nanofibrous aerogels (ECNFAs) that are constructed using ECNFs as building blocks, focusing on the various preparation methods and corresponding structural characteristics, strategies for optimizing mechanical performance, and a wide range of applications. The methods for preparing ECNFs and ECNFAs with diverse structures were initially explored, followed by the implementation of optimization strategies for enhancing ECNFAs, emphasizing the improvement of reinforcing the ECNFs, establishing the bonding effects between ECNFs, and designing the aggregate structures of the aerogels. Moreover, the applications of ECNFAs across various fields are also discussed. Finally, it highlights the existing challenges and potential opportunities for ECNFAs to achieve superior properties and realize promising prospects.
