Poly phthalazinone ether sulfone ketone
WebPoly(phthalazinone-ether-sulfone) (PPES) polymer is a relatively newly developed material with a bis(4-fluorodiphenyl) sulfone group. The formation of the PPES membrane by wet-phase inversion can proceed according to a slow or fast gelation method. These formation mechanisms were studied experimentally. The resulting membrane morphology was … WebNov 19, 2024 · Proton exchange membranes (PEMs) have attracted more and more attention as separators for electrodialysis, electrolysis, pervaporation, fuel cells and flow batteries [1,2,3,4].The key function of PEMs is to efficiently and selectively conduct certain mass while blocking the permeation of the others.
