Abstract

An ultrathin highly fluorinated porous membrane was designed for a large production of desalted water atvery low energy consumption. Imprinting water droplets were used through a low thermally conductivetetra-fluoroethylene (TFE)/2,2,4-trifluoro-5-tri-fluorometoxy-1,3-dioxol (TIT) (HYFLON AD 60) solutionand the generated porous nanofilm was suspended onto a polyethersulfone (PES) honeycomb texture.The very tiny fluorinated thickness together with a large number of small-shaped pores provided themembrane for enhanced anti-wetting surface properties, extremely reduced resistance to water vaportransfer and outstanding thermal efficiency. Fine materials structure-transport relations let the mem-brane reach unusual productivity-efficiency trade-off during water desalination via thermally drivenmembrane distillation. The exceptional performance affords this novel nanostructured membrane tocatalyze the accomplishment of new-concept water desalination processes.
