PREPARATION AND CHARACTERIZATION OF SULFONATED POLYETHERETHERKETONE(SPEEK) NANOFIBROUS MEMBRANE FOR PROTON EXCHANGE MEMBRANE FUEL CELL BY ELECTROSPINNING

摘要

PURPOSE: A manufacturing method of sulfonated polyetheretherketone nano ion exchange membrane is provided to maximize specific surface area, and excellent hydrogen ion conductivity even in high temperature, thereby capable of utilizing as a polymer electrolyte membrane for fuel cell. CONSTITUTION: A manufacturing method of a sulfonated polyetheretherketone nano ion exchange membrane comprises: a step of manufacturing sulfonated polyetheretherketone by reacting polyetheretherketone with chlorosulfonic acid; a step of manufacturing sulfonated polyetheretherketone nanofiber by electrospinning the sulfonated polyetheretherketone; and a step of manufacturing a sulfonated polyetheretherketone nano ion exchange membrane by hot-pressing the sulfonated polyetheretherketone.
