| titleOfInvention | The method of preparing nano-filtration membrane from tree polyamide-amine embedded inorganic nano particles |
| abstract | The invention discloses the methods of preparing nano-filtration membrane from tree polyamide-amine embedded inorganic nano particles, it is related to the preparation method of composite nanometer filtering film.The invention solves organic membrane flux is low, the small problem of the rejection of film.The method of preparing nano-filtration membrane from tree polyamide-amine embedded inorganic nano particles sequentially includes the following steps: one, hydrophilicity-imparting treatment；Two, the dendrimer polyamide-amide aqueous solution containing inorganic nano-particle is prepared, organic phase is prepared；Three, interfacial polymerization prepares polymeric membrane；Four, cross-linking reaction；Five, it cleans.Inorganic nano-particle is introduced into organic polymer systems by the present invention, realize the inierpeneirating network structure of rigid inorganic nano particle and organic polymer, to solve, organic membrane flux is low, and the small problem of the rejection of film is particularly suitable for the preparation field of composite nanometer filtering film. |
