| titleOfInvention | Preparation method of graphene oxide modified triptycenyl polyamide separation membrane |
| abstract | The invention discloses a preparation method of a graphene oxide modified triptycenyl polyamide separation membrane, which comprises the following preparation steps: taking a triptycene compound containing active groups, a diacyl chloride compound and a graphene oxide compound as monomers, and carrying out polymerization reaction in an organic solvent in the presence of an acid-binding agent; pouring the polymer solution obtained by the reaction into deionized water for precipitation, filtering out precipitates, washing the precipitates with methanol and deionized water respectively, and drying to obtain the graphene oxide modified triptycenyl polymer; and dissolving the graphene oxide modified triptycenyl polymer in an organic solvent to prepare a membrane casting solution, coating the membrane casting solution on a support body, and drying to obtain the graphene oxide modified triptycenyl polyamide separation membrane. The invention solves the characteristic of tight accumulation of macromolecules with a reticular structure and breaks the limit of small flux of the traditional triptycenyl polyamide separation membrane. |
