Revolutionizing electrospinning: Sustainable solutions through deep eutectic solvents in biopolymer processing

Abstract

Electrospinning is currently one of the most used techniques for obtaining various types of nanofibers. In the era of sustainable development, it is essential to utilize environmentally friendly raw materials and solvents. This review summarizes the current state of the art in biopolymer electrospinning using deep eutectic solvents. To date, there have not been too many studies on the simultaneous application of these mixtures and biopolymers in the electrospinning process. Nevertheless, the use of natural origin raw materials and the replacement of conventional organic solvents with deep eutectic solvents appear promising in this technique due to many attractive properties of both the mixtures and biopolymers. This article aims to inspire scientists to further research in this direction, related to the development of electrospinning techniques aimed at reducing the negative environmental impact.
