Descripción

General description

Poly(oxy-1,4-phenyleneoxy-1,4-phenylenecarbonyl-1,4-phenylene)(PEEK) is a semi-crystalline polymer with good thermo-mechanical properties and high chemical resistance which can be used as engineering plastics.

Application

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.
