摘要
Provided is a method of preparing a crosslinked sulfonated poly(ether ether ketone) (SPEEK) cation exchange membrane including: preparing a crosslinker mixture of a first crosslinker containing two or more vinyl oxy groups and a second crosslinker containing three or more vinyl groups; preparing a mother liquor containing the crosslinker mixture, a SPEEK polymer substituted with sodium, and a solvent; and casting the mother liquor and then irradiating radiation thereon.
