In the first part of this project, 3,5-dimaleimidobenzoic acid was prepared by reaction of 3,5-diamino benzoic acid with maleic anhydride in chloroform and was characterized. Then sulfonated poly (1,2,3-triazole) (s-PTA) was synthesized by condensation polymerization of the 3,5-dimaleimide benzoic acid and 4,4?-Diazido-2,2?-stilbenedisulfonic acid disodium salt through click cyclization. Chemical structure of synthesized polymer was characterized by FT-IR, 1 H-NMR, elemental analysis, thermogravimetric analysis (TGA). Due to the presence of sulfonated groups in the structure, membrane was prepared from the polymer then the proton conductivity of synthetic sulfonated membrane was studied. The measurements showed that the proton conductivity of the membrane was much higher than the same species because of the presence of amphoteric, sulfonated and carboxylic acid groups on the polymer structure. In the second part of the project, poly (phenylene oxide) was prepared by 2, 6-dimethyl-1,4-phenylene oxide monomer and was tried to achieve polymer with high viscosity. Then obtained polymer was brominated under the condition of radical polymerization that brominated poly(phenylene oxide) was characterized by FT-IR and 1 H-NMR and bipyridine was used in order to produce an ion exchange membrane in the form of crosslinking polymer containing ionic group able to exchange ion. The obtained membrane was characterized by FT-IR, thermogravimetric analysis (TGA), elemental analysis and field emission scanning electron microscopy (FE-SEM). Two Synthesized membrane have potential for using as membrane in proton exchange fuel cell and anion exchange fuel cell, respectively.
