NANOCOMPOSITE ULTRA-THIN SEPARATION MEMBRANE AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a nanocomposite ultra-thin separation membrane and a method for manufacturing the same, wherein the nanocomposite ultra-thin separation membrane for seawater desalination according to the present invention includes: 1) a polyamide-based polymer active layer; 2) a polyethersulfone support membrane; 3) an external support body; and 4) carbon nanotube, to remarkably improve hydrophilicity of the porous support membrane, thereby having more than doubled water permeability of the entire separation film. In addition, due to a physiochemical reaction of the functionalized carbon nanotube, a support membrane exposed to air for a long period of time is also usable as a lower body of the ultra-thin separation membrane.

主权项

1. A nanocomposite ultra-thin separation membrane comprising:
(a) a support body layer; (b) a support membrane layer formed on the support body; and (c) an active layer formed on the support membrane, wherein a functionalized carbon-nanotube is included only in the support membrane layer among the support body layer, the support membrane layer, and the active layer.
