TECHNOLOGY LICENSING OPPORTUNITY: Acid-tuned Terphenyl Membranes (ATM)

Acid-tuned Terphenyl Membranes (ATM) from Los Alamos National Laboratory delivers a fundamentally smarter approach to hydrocarbon proton exchange membrane design, replacing the brute-force strategy of adding more sulfonic acid groups with a precise molecular tweak that strengthens each acid site individually. By installing an electron-withdrawing unit next to the sulfonic acid group, the membrane achieves higher proton conductivity while cutting water uptake by more than half compared to its unmodified counterpart, a combination that provides a promising basis for improved dimensional stability and membrane durability. The result is a hydrocarbon platform that can rival perfluorinated incumbents on performance while opening a path to lower-cost, more sustainable clean energy hardware. How
