Composite semipermeable membrane and method for manufacturing same |
| abstract |
The present invention provides a composite semipermeable membrane that can achieve a high permeation yield and has a high ability to inhibit adhesion to membrane contaminants, and a method for producing the same. The present invention is a composite semipermeable membrane having a supporting membrane comprising a substrate and a porous supporting layer, and a polyamide separation functional layer provided on the porous supporting layer, wherein a hydrophilic polymer containing an acidic group is introduced into the surface of the separation functional layer as an amide bond. It is a composite semipermeable membrane and its manufacturing method. |
