Title:
COMPOSITE HOLLOW FIBER MEMBRANE AND HOLLOW FIBER MEMBRANE MODULE
Document Type and Number:
WIPO Patent Application WO/2013/147187
Kind Code:
A1
Abstract:
This composite hollow fiber membrane comprises a non-porous homogeneous layer which is gas-permeable and a porous support layer which supports said homogeneous layer, and is characterized in that the non-porous homogeneous layer is hydrophobic and the polyolefin resin constituting the porous support layer contains a hydrophilic additive. By this means, a composite hollow fiber membrane for use in degassing can be provided that is hydrophilic, has high water vapor permeability, and can solve the problem of gas permeability being reduced due to condensate in the porous substance.
