Effect of humidity on diameter of polyamide 6 nanofiber in electrospinning process

Various thermoplastic polymers have been spun to nanofibers by the electrospinning method, in which a polymer solution is ejected as a fine jet of liquid from the tip of the needle and is deposited on the collector by applying a high voltage to the polymer solution in the syringe. Due to special cha...
