三维（3D）单片结构（即，由片段化的静电纺丝毡/膜组装的气凝胶/海绵/支架）代表了静电纺丝领域的新兴研究课题。由于极高的孔隙率以及优异的结构柔性和稳定性，这些3D纳米纤维结构在各种应用中吸引了极大的兴趣。在这篇综述中，全面讨论了3D整体结构的制备，以及3D结构的特性及其在环境领域（例如，有机化合物去除，染料吸附，以及过滤和分离），能量（例如，超级电容器），电子器件（例如，压力传感器），化学工程（例如，催化剂载体、热绝缘体和焦耳加热器），和生物医学工程（例如，组织工程、水凝胶和药物递送）进行了总结。此外，还提出了未来的前景和挑战。可以预见，这将提供重要的指导，设计新的三维静电纺丝纳米纤维结构和探索其潜在的应用。
Three-dimensional (3D) monolithic structures (i.e., aerogels/sponges/scaffolds) assembled from fragmented electrospun nanofiber mats/membranes represent an emerging research topic in the electrospinning field. Owing to extremely high porosity, as well as excellent structural flexibility and stability, these 3D nanofibrous structures have attracted significant interests for various applications. In this review, the preparation of 3D monolithic structures are thoroughly discussed; and the properties of 3D structures and their various applications in the fields of environment (e.g., organic compound removal, dye adsorption, and filtration and separation), energy (e.g., supercapacitor), electronics (e.g., pressure sensor), chemical engineering (e.g., catalyst support, thermal insulator, and Joule heater), and biomedical engineering (e.g., tissue engineering, hydrogel, and drug delivery) are summarized. Additionally, the future perspectives and challenges are also presented. It is envisioned that, this review will provide important guidance in designing novel 3D electrospun nanofibrous structures and exploring their potential applications.
