| titleOfInvention | Composite semipermeable membrane and method of manufacturing composite semipermeable membrane |
| abstract | An object of the present invention is to provide a semipermeable membrane having both high permeability and a high salt removal rate. In the present invention, the separation functional layer has a thin film whose main component is polyamide, and the thin film has a pleated structure including a plurality of projections and depressions, and 40% or more of the projections are 25 ° C. The amount of deformation when the convex part is pushed with a force of 5 nN in pure water is 5 nm or less, and the pure water when the 500 mg / L NaCl aqueous solution permeates the composite semipermeable membrane at an operating pressure of 0.5 MPa The permeability coefficient A is 2.0 × 10 −11 m / s / Pa or more, and between the 2-propanol removal rate R when permeating a 500 mg / L 2-propanol aqueous solution at an operating pressure of 0.5 MPa The pore radius r (nm) satisfying the relationship R (%) = 100 × [1− (1−0.232 / r) 2] 2 and the pure water permeation coefficient A satisfy A / r 4> 1.7 × The present invention relates to a composite semipermeable membrane satisfying a relationship of 10-9 m / s / Pa / nm 4. |
