A wide range of polymers can be electrospun to produce nanofibers. Some common polymers include polyethylene oxide (PEO), polyvinyl alcohol (PVA), polycaprolactone (PCL), polyurethane (PU), and poly(lactic acid) (PLA). Additionally, synthetic polymers like polyacrylonitrile (PAN) and polystyrene (PS) are also electrospun. These polymers can be blended or modified with additives to further enhance the properties of the resulting nanofibers.
