This article discusses electrospinning as a method for obtaining nanofibers, some of the challenges and limitations of the technique, advancements in the field, and how it may be used in key functional applications. The key drawbacks of traditional electrospinning processes include relatively slow speed of nanofiber production, low product yield, and relatively high cost. The article also addresses novel high-throughput techniques and methods designed for the scalable synthesis of nanofibers and nanofibrous mats that are of reasonable cost.
