Directional ionic conductivity in two-dimensionally confined structures (A05)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis ; Analytical Chemistry
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 492723217

The project (Breu/Papastavrou) studies anisotropic ion conduction in the confinement between silicate nanosheets, which have huge aspect ratios and electrostatically repel each other in the swollen state. The separation of the nanosheets is controlled by their charging state, the electrolyte concentration, as well as the solvent mixture. The systematic variation of these parameters will allow for elucidating the charge transport properties as a function of nanosheet separation, molecular mobility and mass transport of the dispersion medium. This approach will foster a fundamental understanding of "superionic conductivity" or "ionic current rectification".
