composite semi-permeable membrane |
| abstract |
To provide a composite semi-permeable membrane having more excellent water permeability while maintaining high demineralization property. The composite semi-permeable membrane 1 includes a porous support layer 10 and a separation functional layer 20 formed on the porous support layer 10 and containing aromatic polyamide, the separation functional layer 20 having a plurality of hollow At the same time as having the cell 21, in cross-sectional observation at 8000 times magnification using a transmission electron microscope, the sum of the respective areas of the cells 21 having a cross-sectional area of 1000 nm 2 to 8000 nm 2 is 2.8 μm × 2.8 μm. It is 1.8×10 5 nm 2 to 1.0×10 7 nm 2 in total in two areas. |
