| titleOfInvention | Single-phase hydrophilic polyimide film, method for producing the film, and filtration separator manufactured using the same |
| abstract | The present invention relates to a single-phase hydrophilic polyimide film, a method for producing the film, and a filtration separation device manufactured using the same, wherein (a) a polyimide is a polymer of a monomer represented by Formula 1 or a monomer represented by Formula 2 below: Mid compound; And (b) a single-phase blend comprising a copolymer of a hydrophilic monomer and a hydrophobic monomer, wherein the polymer membrane according to the present invention has a water permeability without lowering the solute removal rate as compared to a conventional polyimide membrane. Significantly improved, since the contamination of the membrane generated when used for a long time as a separation membrane for water treatment can be greatly reduced, the efficiency of the ultrafiltration process, microfiltration process and the like can be greatly improved when used as a separation membrane.n n n [Formula 1]n n n n n n n n (Wherein R 1 and R 2 are each independently hydrogen, a hydroxyl group, a C 1 to C 50 carbon compound, or a C 6 -C 50 aromatic compound.)n n n [Formula 2]n n n n n n n n (Wherein R 1 and R 2 are each independently hydrogen, a hydroxyl group, a C 1 to C 50 carbon compound, or a C 6 -C 50 aromatic compound.)n n n n Hydrophilic Water Treatment Membrane, Hydrophilic Gas Separation Membrane, Hydrophilic Substrate, Polyimide, Polyvinylpyrrolidone, Styrene |
