HIGHLY SWELLABLE COMPOSITE POLYAMIDE MEMBRANE |
| 摘要 |
A method for making a composite polyamide membrane including the step of applying a polar solution including a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the method is characterized by including a tri-hydrocarbyl phosphate within the polar coating solution. The thin film polyamide layer is characterized by possessing an equilibrium water swelling factor of greater than 35% as measured by PFT-AFM. |

1. A method for making a composite polyamide membrane comprising a porous support and a thin film polyamide layer, wherein the method comprises applying a polar solution comprising a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer,
wherein the method is characterized by the polar solution further comprising a tri-hydrocarbyl phosphate compound represented by Formula I: wherein R1, R2 and R3 are independently selected from hydrogen and hydrocarbyl groups comprising from 1 to 3 carbon atoms, with the proviso that no more than one of R1, R2 and R3 are hydrogen, and wherein the thin film polyamide layer is characterized by possessing an equilibrium water swelling factor of greater than 35% as measured by PFT-AFM. |
