| titleOfInvention | Manufacturing method of polyamide based composite membrane and composite membrane thereby |
| abstract | The present invention comprises the steps of applying an aqueous solution containing a polyamine, a tertiary polyamine salt and a polar solvent on the surface of the porous support; And forming a polyamide layer by interfacial polymerization by contacting the porous support coated with the aqueous solution with an organic solution including a polyfunctional acid halogen compound and a nonpolar solvent, and a composite prepared from the composite. Provide a membrane.n n n The polyamide-based composite membrane prepared according to the present invention has a flow rate improvement without a change in salt excretion rate and shows high flow rate characteristics under a lower driving pressure than a conventional separation membrane.n n n n Water treatment, polyamide, tertiary polyamine salt, polar solvent, nonpolar solvent |
