Paper Title:
Synthesis and Characterization of Multi-Sulfonated Poly(Aryl Ether Ketone)s Proton Exchange Membranes
  Abstract

A series of sulfonated poly(aryl ether ketone)s were prepared by condensation polymerization with bisphenol A and 1,2-bis(4-fluorobenzoyl)-3,6-diphenylbenzene, and followed by sufonation with chlorosulfonic acid. The polymers were characterized by Fourier transform infra-red (FTIR) and ion exchange capacity (IEC) to verify sulfonation. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were carried out to investigate the thermal stability of the prepared membranes. The membranes were found to possess all the requisite properties; Ion exchange capacity (3.31meq./g), glass transition temperatures (207-230°C), and low affinity towards methanol (2.04x10-6-4.15x10-7 cm2/S).
