Dehumidification using High-Performance PAN-based Composite Hollow Fiber Membrane
This invention relates to a polyacrylonitrile (PAN)-based membrane suitable for dehumidification and oxygen enrichment, with a proprietary PDMS selective layer. The substrate material is PAN, which is a low cost and commonly available polymer for membrane fabrication. The membrane is made by coating the substrate with the selective layer. The membrane may also be suitable for gas separation, air separation, paraffin-olefin separation, oxygen enrichment, CO2 capture, hydrocarbon recovery, and volatile organic compounds separation.
