Latest Patents
One of his latest inventions is the development of high permeance polyimide membranes for air separation. This invention discloses a new type of polyimide membranes, including hollow fiber and flat sheet membranes, which exhibit high permeances for air separations. The new polyimide hollow fiber membranes have an opermeance higher than 300 GPU and O/N selectivity higher than 3 at 60°C under 308 kPa for O/N separation. Additionally, these membranes demonstrate a CO opermeance higher than 1000 GPU and single-gas selectivity for CO/CH higher than 20 at 50°C under 791 kPa for CO/CH separation. Another notable patent involves photo-crosslinked gas selective membranes as part of thin film composite hollow fiber membranes. This thin film composite membrane comprises a core layer and a sheath UV-crosslinked polymer layer, produced by the co-extrusion of two polymer solutions. The core layer and the sheath layer can be separately optimized, with the sheath layer UV-crosslinked to provide stability and selectivity at the desired operating temperature of the composite membrane.
