Scientists from the The University of Manchester demonstrate the ability to control the interlayer spacing in graphene membranes by physical confinement, paving the way for their use in filtration technologies.
The level of tunability comes from combining pristine graphene and graphene oxide in pre-determined rations, which allows the tuning of the membranes hydrated radius. The different hydrated radii allow permeation of different ions, determined by the ion’s size.
