제목 Preperation and characterization of polyphenylene containing tetraphenyl ketone moiety for PEMFC applications.
초록 Sulfonated poly (phenylene ketone) was synthesized by nickel carbon-carbon polymerization containing benzophenone moiety and tetraphenyl group with ketone for proton exchange membrane, successfully. Sulfonated polymers were prepared by sulfonation reaction with the concentrated sulfuric acid. These polymers have all carbon structure without ether linkages that have the possibility of attack by nucleophiles (made by PEMFC operating system). The polyphenylene structure provides a stiff and resistant backbone, whereas the pendant benzoyl group enables the solubility of the material, and also provides sites for chemical modifications. The properties of membranes investigated by 1H NMR spectroscopy, ion exchange capacity (IEC), water uptake, proton conductivity, atomic force microscope (AFM). The chemical degradation of membranes was performed by Fenton’ reagent and compared with Nafion.
