A unified morphological description of Nafion membranes from SAXS and mesoscale simulations
Builds on Elliott’s earlier highly cited modelling [Phys.Chem.Chem.Phys. 9(2007)2602; DOI:10.1039/b701234a] and experimental studies [Macromolecules 33(2000)4161; DOI:10.1021/ma991113] to present a self-consistent morphology of perfluorosulphonate ionomer membranes used in redox energy storage and power generation. This represents a fundamental step forward from previous work, which either fitted semi-empirical models to scattering data or used numerical models without a direct comparison, thus leading to systematic improvements in actual membrane materials. It featured on inside front cover of Soft Matter (7 August 2011), and led to follow-up funding (EPSRC EP/G030995/1) involving Johnson Matthey (contact: Jonathan Sharman sharmj@matthey.com) on structure of membrane-electrode assemblies.
