Beschreibung
Zusammenfassung:	The present invention relates to a method for preparing mesoporous magnesium titanate, a carbon dioxide separation membrane using graft copolymers and a preparation method thereof and, more specifically, to a method for preparing mesoporous magnesium titanate, capable of improving both transmittance and selectivity by solving a problem caused by a characteristic of a gas separation membrane in which selectivity is reduced while transmittance is enhanced, to a carbon dioxide separation membrane using graft copolymers and to a preparation method thereof. To this end, the carbon dioxide separation membrane using the graft copolymers is prepared by using a polymer matrix and a template of a nanostructure as the same material.
