Abstract
Metallophthalocyanine (MPc) is a potent catalyst for hydrogen peroxide oxidation(H2O2→ 2H++ O2+ 2e?). The properties of membranes with and without MPc have been studiedin this study. Poly(ether sulfone)s containing MPc (Ni and Co) (PMPc) were prepared by two-step reac-tion from 1,4-bis(4-hydroxyphenyl)-2,3-dicyanonaphthlene, 4,4-biphenol and 4,4-fluorophenylsulfone,and were followed reaction with metal (II) chloride (Ni and Co) and 1,2-dicyanobenzene in quinoline.The sulfonated PMPc (SPMPc) were synthesized by sulfonation reaction of PMPc with chlorosulfuricacid in methylene chloride. All these membranes were casted from dimethylacetamide (DMAc). Thestructural properties of the synthesized polymers were investigated by1H NMR spectroscopy and FT-IR.The membranes were studied by ion exchange capacity (IEC), water uptake, and proton conductivity.These membranes were then subjected to a deterioration test by Fenton reagent and compared withnormal sulfonated poly(ether sulfone)s and Nafion in order to determine the role of MPc. Membranescontaining MPc was shown to have better chemical stability that those without MPc.
