Barr, Kunal Karan, Jos Cooper, Mario Campana, Daniel J. L. Brett, Thomas S. Miller, Sandrine Lyonnard, Fabrizia FogliaUsing multimodal neutron scattering we probe how additive chemistry and structure direct PFSA nanocomposite morphology, water organisation and ionic-domain connectivity critical to membrane conductivity, gas crossover, and durability.
