To overcome the drawback of hydrocarbon membrane, there are three types of carbon-carbon structured polymer main chain, such as Diels-Alder, superacid, Ni/Zn catalyzed polymerization. Among them, we have successfully synthesized polymer with comonomers of multi-penyl ketone and dibenzophenyl-dichlorobenzene using a Ni/Zn catalyst. The sulfonated polymer have good morphology and durability than other sulfonated polymer with ether linkege. 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. |
