METHOD OF FABRICATING NANOPOROUS ORGANIC-INORGANIC HYBIRD FILM AND NANOPOROUS ORGANIC-INORGANIC HYBIRD FILM MANUFACTURED BY THE METHOD AND NANOPOROUS MEMBRANE EMPLOYING THE NANOPOROUS ORGANIC-INORGANIC HYBIRD FILM

摘要

Provided are a method for manufacturing a nanoporous organic-inorganic hybrid film, the nanoporous organic-inorganic hybrid film manufactured by the same, and a nanoporous separation film using the same. More specifically, the present invention provides a method for manufacturing a nanoporous organic-inorganic hybrid film, which comprises the following steps: preparing an organic sol containing a compound having an amino group, a compound having an isocyanate group, and a solvent; producing a mixed solution by adding an inorganic oxide precursor to the organic sol; and forming an organic molecule net structure in which the organic sol is pectized and an inorganic molecule net structure positioned along the surface of the organic molecule net structure by thermally treating the mixed solution. The method of the present invention is capable of easily manufacturing the nanoporous organic-inorganic hybrid film with a three-dimensional fine structure through the simple manufacturing process using the pectization of the organic sol and a condensation reaction of the inorganic oxide precursor. In addition, the nanoporous separation film using the nanoporous organic-inorganic hybrid film having a wide specific surface area can have high transmittance and high solute removing efficiency.
