| titleOfInvention | Polyarylether ultrafiltration membrane, nanofiltration membrane, preparation method and method for reversible conversion of ultrafiltration membrane and nanofiltration membrane |
| abstract | The invention relates to a polyarylene sulfide ultrafiltration membrane containing a tertiary amine structure, a polyarylene sulfide nanofiltration membrane containing a tertiary amine structure and a preparation method thereof, belonging to the field of high polymer materials. The invention provides a polyarylene sulfide separation membrane, which is a tertiary amine-containing polyarylene sulfide ultrafiltration membrane prepared from tertiary amine-containing polyarylene sulfide resin. The invention provides a novel ultrafiltration separation membrane, wherein an obtained ultrafiltration membrane can be converted into a nanofiltration membrane through acidification treatment; the nanofiltration membrane can be recovered into an ultrafiltration membrane through deacidification treatment, and then the reversible conversion of ultrafiltration and nanofiltration is realized. |
