Description
PEEK can be sulfonated and coated on nanofiltration(NF) membranes which can be used in the fabrication of antifouling based NF membranes. Sulfonated PEEK (up to 50-70 degree of sulfonation(DS)) can be used in the formation of proton exchange membranes(PEMs) for fuel cells based applications.Related product price
