Composite semipermeable membrane and method for producing the same |
| abstract |
[PROBLEMS] To provide a composite semipermeable membrane that separates and removes contaminants and has high water permeability even at low pressure. SOLUTION: This is a composite semipermeable membrane in which an ultrathin film layer of a crosslinked polyamide is formed on a microporous support film, and the concentration of hydrophilic groups in the ultrathin film layer analyzed by X-ray photoelectron spectroscopy (ESCA) is reduced. A composite semipermeable membrane characterized by being 0.017 to 0.1. |
