Separation membrane and method for producing separation membrane |
| abstract |
A separation membrane having excellent chemical resistance and high water permeability is provided. A separation membrane includes a porous support, a polyamide-based separation functional layer provided on the porous support, and a coating layer provided on the polyamide-based separation functional layer. The zeta potential at pH 3 of the surface of the layer is -9 mV or less. [Selection drawing] Fig. 1 |
