Upon electrification, the surface tension is brought out by the extruded droplet, and the electrostatic repulsion among charges on the surface of the droplet competes with the surface As mentioned above, it is necessary to prepare the polymer nanofibers as the precursor for the fabrication of CNFs, and during electrospinning, different tunable parameters are empowered to freely produce nanofibers enriched with unique physicochemical properties, and outstanding functional characteristics . The polymer solution, and the processing parameters decide the properties of the final CNFs. To fabricate CNFs, the major criteria for choosing the precursor is to have any fibrous material with a carbon backbone.
