APPARATUS FOR PRODUCING NANOFIBER BY ELECTROSPINNING METHOD USING DOUBLE-PIPE NOZZLE AND NANOFIBER PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To continuously produce a nanofiber by using a double-pipe nozzle composed of an inner pipe and an outer pipe in a nanofiber production apparatus by an electrospinning method.;SOLUTION: The apparatus for producing the nanofiber by an electrospinning method is provided with a nozzle, a collector placed opposite to the nozzle and collecting nanofibers, and a high-voltage direct current electric source to apply an electric potential between the nozzle and the collector. The nozzle is the double-pipe nozzle composed of the inner pipe and the outer pipe, an organic polymer solution supplied by a syringe pump 1 is ejected from the inner pipe, a solvent supplied by another syringe pump 2 is ejected from a ring-formed gap between the inner pipe and the outer pipe of the double-pipe nozzle in a manner to encircle the circumference of the inner organic polymer solution with the solvent to prevent adsorption of the nanofiber to the nozzle.;COPYRIGHT: (C)2011,JPO&INPIT
