Sulfonated polymerized liquid crystal nanoporous membranes for water purification

New isoporous nanofiltration composite membranes were fabricated by photo-polymerization of thin films the hexagonal columnar mesophase supramolecular complex 43TB. This was followed deposition on a polyether sulfone macro-porous support and removal template molecule. The had an average permeability 2.3 L m-2 h-1·bar-1 sharp molecular weight cut-off around 5000 g mol-1 based PEG filtration. full rejection Bovine Serum Albumin Green fluorescence proteins their flux recovery suggested absence defects LC layer membrane. filtration charged molecules presented total for larger than 1000 size-charge selectivity with higher cationic due to ionic interactions pore walls. These mean absorption within membrane, which has effect neutral solutes such as Riboflavin 3000, being less relevant smaller molecules.
