Title:
COMPOSITE SEMIPERMEABLE MEMBRANE
Document Type and Number:
Japanese Patent JP2021090953
Kind Code:
A
Abstract:
To provide a composite semipermeable membrane that is excellent in fouling resistance and that enables a stable desalting treatment to be executed over an extended period of time.SOLUTION: A composite semipermeable membrane comprises a porous support membrane, a separation function layer including a polyamide provided on the porous support membrane, and a coating layer provided on the separation function layer. A water contact angle of a surface of the coating layer is 40° or less. Protein adsorbability of the surface of the coating layer is 0.4 nN or less.SELECTED DRAWING: Figure 1
