Composite semipermeable membrane, preparation method thereof, and element, fluid separation device and water treatment method using same |
| abstract |
The present invention provides a composite semipermeable membrane comprising a separating functional layer containing polyamide formed on a porous support film, wherein the average pore radius of the separating functional layer including polyamide, measured by a positron extinction lifetime spectroscope, is 0.25 nm to 0.35 nm. And a porosity of 0.2 nm 3 % to 0.3 nm 3 %. |
