Abstract: PURPOSE: A method for fabricating ionic liquid supported liquid membrane for gas separation is provided. The method uses ionic liquid which maintains liquid status over a wide temperature range and has no vapor pressure as liquid membrane raw material, and produces liquid membrane by phase separation process, so that the method can uniformly disperse ionic liquid to a support polymer and easily produce stable liquid membrane. CONSTITUTION: The method comprises the steps of (a) preparing ionic liquid being kept in liquid phase over a wide temperature range and having no vapor pressure, (b) preparing a support polymer with low gas permeability and good mechanical properties, (c) dissolving the prepared ionic liquid and the support polymer in a common solvent, (d) making a film using a solution obtained at the step (c), (e) removing the common solvent by phase separation in which a first phase separation process is performed at a temperature of 20 to 40°C and relative humidity of 30 to 40% and a second process is performed at a temperature of 60 to 90°C, thereby producing a domain in which ionic liquid is immobilized into a support polymer, wherein the ionic liquid is 1-alkyl-3-methylimidazolium cation and the polymer is selected from a group consisted of polyvinylidene fluoride, polyacrylonitrile, polysulfone, cellulose acetate, and polyvinylidene fluoride copolymer.

Abstract: PURPOSE: To separate volatile organic compounds from waste stream effectively, a hybrid membrane which is composed of porous membrane layer and non-porous membrane layer is provided. The porous membrane layer has the ability of concentration and has an effect on the characteristic of separation, whereas the non-porous membrane layer has the ability of purification and an affinity for volatile organic compounds. The hybrid membrane can improve the effectiveness of separation by picking out the merits of porous and non-porous membrane layers. CONSTITUTION: The hybrid membrane comprises a porous membrane layer which has the ability of concentration and a non-porous membrane layer which is coated with macromolecules that have an affinity for volatile organic compounds. On one side of the porous layer, a solution containing fillers, including aluminum nitrate, aluminum sulfate, calcium chloride and polyethylene oligomer, is applied, whereas on the other side of the porous layer, negative pressure of 5-300 torr is applied. After forming a porous layer on one side, polydimethyl siloxane oligomer is applied the other side so that a non-porous layer is formed.
