摘要

PROBLEM TO BE SOLVED: To provide a silicone-containing organic solvent-resistant polyamide nano-composite membrane and a manufacturing method therefor.;SOLUTION: The silicone-containing organic solvent-resistant polyamide nano-composite membrane having an excellent exclusion ratio and extremely excellent not only in organic solvent resistance but also in permeability to the solvent is manufactured by applying silicone to a porous support during the polyamide polymerization process on the surface of the porous support. The manufacturing method for the nano-composite membrane is also disclosed. The nano-composite membrane can be adapted to the refining of a mixed organic solvent and organic solvent wastewater treatment and is especially effective for recovering a low-molecular-weight organic compound (molecular weight: 100-1,000) dissolved in an organic solvent. Accordingly, this nano- composite membrane can be widely adapted to the separation of oil in the oil refining industry, the separation and recovery of an expensive catalyst, the separation and concentration of a chemical agent and the separation of a toxic substance.;COPYRIGHT: (C)2004,JPO
