Composite Semipermeable Membrane and Manufacturing Method Thereof |
| abstract |
An object of the present invention is to provide a composite semipermeable membrane capable of realizing excellent fouling resistance over a long period of time. The present invention comprises a support membrane (substrate and porous support layer) and a separation functional layer provided on the porous support layer and comprising a crosslinked polyamide and a hydrophilic polymer, and the condition (A) (the hydrophilic polymer has a positive charge) The present invention relates to a composite semipermeable membrane containing a functional group and a functional group having a negative charge, wherein the hydrophilic polymer is negatively charged) and (B) (the hydrophilic polymer is covalently bonded to the crosslinked polyamide). |
