| abstract |
The present invention relates to a method of manufacturing a polyamide composite membrane using a sulfur-doped nano-carbon material, the step of doping sulfur into a nano-carbon material, adding and dispersing a nano-carbon material to a first solution containing a polyfunctional aromatic amine Immersing the porous support in the first solution, immersing the porous support in a second solution containing a polyfunctional acyl halide, and drying the porous support at 60 to 80°C for 30 to 60 minutes. do. |
