Trends and developments in the manufacturing of polymer nanofibrils with the electrospinning technique

Electrospinning is a technique that is exceptionally well-suited for reliable, cost-effective production that uses electrostatic forces to form and manipulate a jet of polymer solution to form nano-sized, fibrillar polymeric materials. However, producing smooth (non-beaded) fibres with truly nano-sized diameters is not an easy task and is highly influenced by polymer selection. Substantial versatility also exists in the properties and morphologies of the nanomaterials produced with this method. Knowledge of the fundamental features and current trends within the sector of electrospinning are enabling the reliable, effective production of materials that would be most suitable for a variety of applications. This article will discuss each of these issues and will demonstrate the usefulness of the electrospinning technique with a brief overview of the key applications of interest including those which have obtained commercial success. Overall, this article will demonstrate how electrospinning is a unique and effective tool that continues to develop at a rapid pace, with substantial commercial potential yet to be unlocked.
