Research Theme - 2： Material Analyses using Quantum Beams
2-1 Structure Analyses of Grafted Polymer Electrolyte Membranes by Small Angle Neutron Scattering
The number of water molecules hydrated with ion-exchange groups in ion-exchanged membranes are determined by Contrast Variation Small-Angle Neutron Scattering (CV-SANS) combined with Partial Scattering Function (PSF) analysis. This new analysis method helps understanding of nanoscale structure of ion-exchange membrane.
2-2 Structure Analyses of High Durable & High Conductive Anion-exchange Electrolyte Membranes
The hierarchical structure of conductive anion-exchange electrolyte membrane was clarified using Partial Scattering Function (PSF) Analysis through Contrast Variation Small-Angle Neutron Scattering (CV-SANS).
2-3 Multiscale Structural Analyses of Electrolyte Membranes for Fuel Cell
The performance of electrolyte membranes for fuel cell depends on its conductivity that is deeply related with the density of sulfonic acid group (SO3H）in the membranes. The multiscale analyses of the membranes have been conducted to understand the structure of water channels that control the mobility of H+ from one SO3H to another in the membrane.
