New type of membrane material for water desalination based on a cross-linked bicontinuous cubic lyotropic liquid crystal assembly
A new type of nanoporous polymer capable of efficient water desalination and nanofiltration has been demonstrated. This material, which is based on a cross-linked QI-phase lyotropic liquid crystals assembly, has an effective pore size of 0.75 nm and is capable of high salt rejection, with a water permeability similar to that of commercial reverse osmosis membranes in dead-end filtration. Currently exploring new processing methods that afford thin QI films and larger area samples so that cross-flow studies can be performed are explored. It was also explored hether the water manifold gap size and permeability of the material can be tuned by modifying the structure of the lyotropic liquid crystals monomer, as well as the design of more readily synthesized QI phase monomers.
