At the University of Chicago, researchers have quietly resolved one of membrane science's most persistent contradictions: that making a membrane more conductive to ions has always meant making it absorb more water, and vice versa. By studying the flexibility of polymer backbones at the molecular level, the team found that structure itself can be designed to create efficient ionic pathways without the cost of instability. The insight points toward a generation of greener, more capable membranes that could underpin fuel cells, electrolyzers, and water treatment systems at the heart of the energy
