Abstract Short nanofibers have been of interest in preparing 3D porous structures, aerosol filters, and nanocomposites. These materials require nanofiber retrieval and application in short form with simultaneous control over aspect ratio. Electrospinning, conventionally, offers minimal control over short nanofiber yield as nonwoven mat is the default configuration of collected sample. High surface area to volume ratio nanofiber, however, can offer new vistas in material design if standardization of short nanofiber preparation practices, offering control over aspect ratio, can be attained. It will provide novel insights into design of tissue engineering scaffolds, filtration membranes, and nanocomposite properties. This work summarizes reported efforts to prepare short nanofiber through mechanical, chemical, material, and operational variables. It aims to provide comparative glance at attempts to control aspect ratio along with pros and cons of the adopted techniques. Lastly, discussion shares generalized conclusions and insights gathered while reviewing material and operational variables adopted for short nanofiber preparation.

复合增强材料短电纺纳米纤维制备技术综述

摘要 短纳米纤维在制备 3D 多孔结构、气溶胶过滤器和纳米复合材料方面引起了人们的兴趣。这些材料需要以短形式检索和应用纳米纤维，同时控制纵横比。传统上，静电纺丝对短纳米纤维产量的控制最小，因为非织造垫是收集样品的默认配置。然而，如果能够实现短纳米纤维制备实践的标准化，提供对纵横比的控制，那么高表面积与体积比的纳米纤维可以为材料设计提供新的前景。它将为组织工程支架、过滤膜和纳米复合材料特性的设计提供新的见解。这项工作总结了通过机械、化学、材料、和操作变量。它旨在提供对控制纵横比的尝试以及所采用技术的优缺点的比较概览。最后，讨论分享了在审查用于短纳米纤维制备的材料和操作变量时收集的一般性结论和见解。
