摘要： Provided are a composite semipermeable membrane capable of enhancing adhesion between a separation functional layer provided with a coating layer and a protective tape while maintaining an effect of the coating layer to some extent, and a spiral membrane element using the composite semipermeable membrane.
A composite semipermeable membrane includes: a porous support; a separation functional layer formed on the porous support; and a coating layer provided on a surface of the separation functional layer, the coating layer having different surface roughnesses due to different adhesion amounts of a coating material depending on locations. The composite semipermeable membrane has a coating layer-side surface on which a glossy portion having a surface roughness Ra of 30 nm or less and a non-glossy portion having a surface roughness Ra of 50 nm or more are provided.

摘要： Composite polyether block amide (PEBA) copolymer tubes incorporate an ultra-thin PEBA extruded layer that enables rapid moisture transfer and exchange through the tube. An extruded composite PEBA film may include a porous scaffold support and may be formed or incorporated into the composite PEBA tube. An extruded PEBA may be melted into pores of a porous scaffold support. Extruded PEBA may be wrapped on a mandrel or over a porous scaffold support to form a composite PEBA tube. A film layer may be applied over a wrapped composite PEBA film to secure the layers together. A support tube may be configured inside or outside of the PEBA tube.

摘要： Nanofiltration membranes and methods of using and making thereof are disclosed. The nanofiltration membranes contain a silk layer, a porous substrate, and a selective layer. The silk layer is an interlayer sandwiched between the porous substrate and selective layer. The nanofiltration membranes have high performance for filtering water, such as improved water permeance and/or high ion removal rate. For example, the nanofiltration show a water permeance that is at least 2-fold, such as about 5-fold, of the water permeance of a commercially available nanofiltration membrane, such as DuPont FilmTec™ NF270 and/or DuPont FilmTec™ NF90, and an ion rejection of at least 70% against a target ion, such as a divalent or multivalent ion. The greatly improved water permeance of the nanofiltration membranes can result in up to a magnitude lower energy consumption in water filtration applications.
