We are exploring mass transport phenomena in such molecular environment as 2D hydrogen bonding network of water and short-range polymeric pathways. For example, water molecules confined in between 2D materials can obtain unique transport properties affecting permeability and selectivity. We investigate the behavior of this 2D confined water sandwiched within lamellar molybdenum disulfide (MoS₂), finding the evidence of non-continuum hydrodynamics as well as ion sieving. Also, by cutting its thickness, we increase the permeability of a polymer membrane while keeping the inherent selectivity. To secure its in-operando stability, we design a composite nanofilm comprising a carbon nanotube template, polymer fillers, and functional additives, resulting in outperforming the polymer-only counterpart.
