ABSTRACT
Unlike conventional fiber spinning techniques, wet spinning, dry spinning, melt spinning, and gel spinning, which are capable of producing polymer fibers with diameters down to the micrometer range, “electrospinning” is capable of producing polymer fibers in the nanometer diameter range. Nanofibers have a high specific surface area due to their small diameters, and nanofiber mats can be highly porous with good pore interconnection. Electrospinning is a simple and versatile method for generating ultrathin fibers from a rich variety of materials that include polymers, composites, and ceramics, that is, poly(vinyl acetate) is used as a carrier polymer for preparation of conductive or inorganic nanofibers. For fiber production using electrostatic forces, electrostatic spinning relies on an electrically charged jet of polymers or liquid states of polymers in order to make fibers from microdimensions to nanodimensions. Blow spinning technique is used to obtain electroactive fibers are through the application of a static electric field on a polymer solution or melt.
