Laminar MoS2 membranes show outstanding potential for practical applicationsin energy conversion/storage, sensing, and as nanofluidic devices. For waterpurification technologies, MoS2 membranes can form abundant nanocapillariesfrom layered stacks of exfoliated MoS2 nanosheets. These MoS2 membranes havepreviously demonstrated excellent ionic rejection with high water permeationrates, as well as long-term stability with no significant swelling when exposedto aqueous or organic solvents. Chemical modification of these MoS2 membraneshas been shown to improve their ionic rejection properties, however themechanism behind this improvement is not well understood. To elucidate thismechanism we report the potential dependant ion transport throughfunctionalized MoS2 membranes. The ionic permeability of the MoS2 membrane wastransformed by chemical functionalization with a simple naphthalene sulfonatedye (sunset yellow) and found to decrease by over a factor of ~10 compared tothe pristine MoS2 membranes and those reported for graphene oxide and Ti3C2Tx(MXene) membranes. The effect of pH, solute concentration, and ionicsize/charge on the ionic selectivity of the functionalized MoS2 membranes isalso reported. The potential dependant study of these dye functionalized MoS2membranes for ionic sieving with charge selectivity should enable futureapplications in electro-dialysis and ion exchange for water treatmenttechnologies.
