Hanqing's research article on conductivity-permselectivity tradeoffs of ion-exchange membranes has been accepted for publication in the Journal of Membrane Science.
The structure-property analysis integrated counterion condensation theory with Nernst-Planck transport framework to elucidate the intrinsic conductivity-permselectivity tradeoffs in electrodialysis and reverse electrodialysis. Key findings of the study include i) higher bulk solution concentration elevates conductivity but lowers permselectivity due to diminished co-ion exclusion, ii) increasing ion-exchange capacity enhances both conductivity and permselectivity, iii) raising swelling degree improves conductivity but compromises permselectivity, and iv) reducing membrane thickness lowers resistance while preserving permselectivity.
