Title:
MODIFIED POLYTETRAFLUOROETHYLENE, MANUFACTURING METHOD THEREFOR, ION EXCHANGE MEMBRANE USING SAME, AND METHOD FOR MANUFACTURING ION EXCHANGE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2020/166988
Kind Code:
A1
Abstract:
The present invention can provide an ion exchange membrane for a fuel cell, the ion exchange membrane comprising polytetrafluorethylene (PTFE) hydrophilically modified through a reaction with a modification mixture solution containing a phenolic compound and polyethyleneimine (PEI), wherein the modified polytetrafluoroethylene is coated with a hydrocarbon-based polymer, whereby the ion exchange membrane exhibits excellent mechanical properties and improved dimensional stability and can be prevented from decreasing in ion conductivity.
