| titleOfInvention | Borate intercalation modified graphene oxide composite nanofiltration membrane and preparation method thereof |
| abstract | The invention discloses a borate intercalation modified graphene oxide composite nanofiltration membrane and a preparation method thereof. The modified graphene oxide is modified by adopting borate as an intercalation molecule, and then the modified graphene oxide is connected with a hydrolyzed polyacrylonitrile film through polyethyleneimine to obtain the composite nanofiltration membrane. According to the invention, borate is used as an inorganic covalent cross-linking agent to intercalate and modify the layered graphene oxide nanosheets, the distance between graphene oxide layers is increased before film formation, so that the problem of environmental pollution caused by organic small molecule intercalation is solved, and the distance between graphene oxide layers is increased so as to improve the permeation flux and separation performance of the film; and the reaction condition of the preparation process is mild, and the cost is low. |
