| titleOfInvention | A kind of preparation method of phosphonic chloride monomer, Nano filtering composite membrane and Nano filtering composite membrane |
| abstract | The present invention provides a kind of phosphonic chloride monomer, has structure shown in Formulas I, wherein R is-PO (Cl) 2 Or-OPO (Cl) 2 , R 1 、R 2 、R 3 、R 4 And R 5 It is independent to be selected from-H ,-COCl ,-PO (Cl) 2 Or-OPO (Cl) 2 , and R 1 、R 2 、R 3 、R 4 And R 5 It is not simultaneously-H.The present invention also provides a kind of Nano filtering composite membranes and preparation method thereof.The present invention will have-PO (Cl) 2 The phosphonic chloride monomer of group is for utilizing-PO (Cl) in the preparation process of Nano filtering composite membrane 2 A large amount of-PO (OH) is generated in reaction process 2 Group realizes the purpose for increasing active layer negative charge amount.And the space structure of the phosphonic chloride monomer in the present invention makes active layer have of a relatively loose structure, finally realizes the equilibrium state an of sieving actoion and electrical charge rejection effect.While guaranteeing compared with equipment with high desalinization, permeation flux has large increase. |
