Introduction and Fundamentals of Electrospinning

Advances in Electrospun Materials and Methods for Li-Ion Batteries

“…The electrospinning process can be made more energy-efficient by adopting the following strategies: (i) use of direct-current electrospinning instead of traditional high voltage electrospinning as a comparatively lesser voltage is used making the process energy efficient [ 168 , 169 ]; (ii) powering the electrospinning equipment using renewable energy resources, such as solar panels and wind turbines, which can reduce the carbon footprint of the electrospinning process [ 170 , 171 ]; (iii) usage of renewable or biodegradable materials to prepare the fibers as these materials can be broken down in the environment, reducing the amount of energy needed for disposal [ 172 , 173 ]; (iv) to achieve appropriate end-of-life disposal of the electrospun fibers by recycling or composting the fibers as it can reduce the amount of energy required for disposal; (v) reusing the syringe after flushing the polymer melt left after processing using the appropriate solvent [ 174 ]; (vi) optimize the process by reducing the waste generated or recycling excess material that is not used in the fiber-formation process [ 175 ].…”

Electrospun Nanofibers for Biomedical, Sensing, and Energy Harvesting Functions

“…One-dimensional nanomaterials in the form of nanofibers have a wide-ranging spectrum of research and commercial applications, due to their exceptional physicochemical properties and characteristics. Electrospinning is a relatively simple, yet versatile and promising method for the production of nanofibrous materials for a wide variety of applications [1][2][3][4][5][6][7][8]. A typical electrospinning apparatus consists of a high-voltage power supply to generate an electrical field, a syringe pump with speed and volume control to provide the polymer or polymer blend flow rate, and a collector plate on which the nanofibers to be formed are deposited.…”
