Latest Patents

Gulver holds a patent for "Proton exchange membrane materials based on sulfonated poly (phthalazinones)." This novel class of materials was prepared through the modification of poly(phthalazinone). The sulfonation reactions were conducted at room temperature using mixtures of concentrated sulfuric acid and fuming sulfuric acid. The resulting sulfonated poly(phthalazinones) exhibit a degree of sulfonation ranging from 0.6 to 1.0. The presence of sulfonic acid groups was confirmed by FT-IR analysis, while NMR was used to characterize the degree of sulfonation and structures. The introduction of sulfonic groups into the polymer chains resulted in an increase in the glass transition temperature and a decrease in the decomposition temperature. Membrane films were cast from solutions in N,N-dimethylformamide or N,N-dimethylacetamide. Notably, the water uptake and swelling ratios of the membrane films increased with the degree of sulfonation, with sulfonated polymers having a degree of sulfonation greater than 1.2 being water-soluble at 80°C. Furthermore, proton conductivity increased with the degree of sulfonation and temperature, reaching values of 10 S/cm at 95°C.
