Abstract

Aerogel fiber has broad applications in thermal insulation, pollution adsorption, biomedicine, energy storage, and aerospace. However, the large-scale and continuous production of aerogel fibers remains a significant challenge. Wet spinning technology transforms the static sol–gel process into rapid dynamic gel fiber molding, and is the preferred spinning method for continuous molding and large-scale production of aerogel fibers. This review provides a systematic overview of the production process of wet-spun aerogel fibers and the obstacles it encounters in the forming and drying stages. It also discusses the progress of different spinning strategies in optimizing the structure and properties of aerogel fibers. Recent advances in the properties of aerogel fibers, such as thermal insulation, adsorption, and optical and electromagnetic shielding, which are affected by the structural characteristics of aerogel fibers, are presented. Finally, this review provides a brief conclusion and discusses the technical challenges and future directions for wet-spun aerogel fibers. This review is expected to offer fresh perspectives and innovative strategies for the continuous production of aerogel fibers, the development of high-performance and multifunctional aerogel fibers, and their diverse applications.

气凝胶纤维湿法纺丝技术：开拓高性能和多功能材料的前沿领域

气凝胶纤维在保温隔热、污染吸附、生物医学、能源储存和航空航天领域有着广泛的应用。然而，气凝胶纤维的大规模连续生产仍然是一项重大挑战。湿法纺丝技术将静态溶胶-凝胶过程转变为快速动态凝胶纤维成型，是连续成型和大规模生产气凝胶纤维的首选纺丝方法。本综述系统地概述了湿法纺丝气凝胶纤维的生产过程及其在成型和干燥阶段遇到的障碍。文章还讨论了不同纺丝策略在优化气凝胶纤维结构和性能方面取得的进展。此外，还介绍了气凝胶纤维性能的最新进展，如隔热、吸附、光学和电磁屏蔽等受气凝胶纤维结构特性影响的性能。最后，本综述作了简要总结，并讨论了湿纺气凝胶纤维面临的技术挑战和未来发展方向。本综述有望为气凝胶纤维的连续生产、高性能和多功能气凝胶纤维的开发及其多样化应用提供新的视角和创新战略。
