New sulfonated copoly(triazole imide)s by click chemistry with improved oxidative stability

Abstract

Novel soluble sulfonated copoly(triazole imide)s with different ion exchange capacities were synthesized by click reaction. The structures of the resulting copoly(triazole imide)s were characterized by FTIR and 1H NMR spectroscopy techniques. These copoly(triazole imide)s were soluble in different organic solvents and form flexible films with good mechanical property along with high thermal stability. The presence of triazole and flexible moieties contributed in improving oxidative stability and swelling properties. The proton conductivities of copolymers were found in the range of 15-98 mScm-1 at 90 °C in water. Transmission electron microscopy analysis was used to observe the microstructure of the copolymers as as evidence of microphase separation of ionic and hydrophobic domains.
