A Review on Current Nanofiber Technologies: Electrospinning, Centrifugal Spinning, and Electro‐Centrifugal Spinning

Nanofiber-based products are widely used in the fields of public health, air/water filtration, energy storage, etc. The demand for nonwoven is rapidly increasing especially after COVID-19 pandemic. Electrospinning most popular technology to produce nanofiber-based from various kinds materials bench and commercial scales. While centrifugal spinning electro-centrifugal considered be other two well-known technologies fabricate nanofibers. However, their developments restricted mainly due unnormalized devices principles. High solution concentration high production efficiency main strengths spinning, but beaded fibers can formed easily air perturbation or device vibration. Electro-centrifugal by introducing a voltage electrostatic field into system, which suppresses formation results producing elegant It believed that electrospinning replaced some specific application areas. This article gives an overview on existing crucial processing parameters these nanofiber technologies, also constructive suggestions proposed facilitate development spinning.
