POSITIVE ION EXCHANGE FILM GRAFTED ON THE SURFACE OF A NANOFIBER WITH A SINGLE PROCESS USING A RADIATION GRAFT POLYMERIZATION, AND A PRODUCING METHOD THEREOF

摘要

PURPOSE: A positive ion exchange film and a producing method thereof are provided to secure the larger diameter of a nanofiber than a conventional nanofiber, and to improve the hydrogen ion conductivity.;CONSTITUTION: A producing method of a positive ion exchange film comprises a step of grafting a vinyl monomer, a polymer, or sodium styrene sulfate on the surface of nanofiber using a radiation graft polymerization with a single process. The nanofiber is selected from the group consisting of polyvinylidene fluoride(PVDF), polyamide, polyester, polysulfone, polyethylene, polypropylene, and cellulose.;COPYRIGHT KIPO 2011
