Publication number: 20200324252Abstract: An air-impermeable water vapor transport membrane comprises an active layer on a microporous polymeric substrate. The active layer comprises a polyethylene-oxide containing copolymer and a polar protic solvent in an amount of about 3% to about 100% of copolymer weight in the active layer. Molecules of the protic solvent are bonded to the copolymer. The polar protic solvent reduces temperature-dependent variability in the water-vapor permeability of the membrane.Type: ApplicationFiled: January 16, 2020Publication date: October 15, 2020Inventors: Ryan Nicholas HUIZING, Hao CHEN, Frankie Kin Bong WONG

Patent number: 9517433Abstract: A water vapor transport membrane comprises a nanofibrous layer disposed on a macroporous support layer, the nanofibrous layer coated with a water permeable polymer. A method for making a water vapor transport membrane comprises forming a nanofibrous layer on a macroporous support layer and applying a water permeable polymer to the nanofibrous layer. The water permeable polymer can be applied for so that the nanofibrous layer is substantially or partially filled with the water permeable polymer, or so that the coating forms a substantially continuous layer on one surface of the nanofibrous layer. In some embodiments of the method, the nanofibrous layer is formed by electro-spinning at least one polymer on at least one side of the porous support layer. In some embodiments, the support layer is formable and the method further comprises forming a three-dimensional structure from the water vapor transport membrane, for example, by compression molding, pleating or corrugating.Type: GrantFiled: November 6, 2014Date of Patent: December 13, 2016Assignee: DPOINT TECHNOLOGIES INC.Inventors: Ryan Nicholas Huizing, Frank K.

Publication number: 20160109184Abstract: Coated membranes comprise a porous desiccant-loaded polymer substrate that is coated on one surface with a thin layer of water permeable polymer. Such membranes are particularly suitable for use in enthalpy exchangers and other applications involving exchange of moisture and optionally heat between gas streams with little or no mixing of the gas streams through the membrane. Such membranes have favorable heat and humidity transfer properties, have suitable mechanical properties, are resistant to the crossover of gases when the membranes are either wet or dry, and are generally low cost.Type: ApplicationFiled: December 21, 2015Publication date: April 21, 2016Inventor: Ryan Nicholas HUIZING
