Abstract: The present invention relates to a method for manufacturing a polymeric membrane for gas separation and a polymeric membrane for gas separation manufactured thereby. An object of the present invention is to provide a method for manufacturing a polymeric membrane for gas separation and a polymeric membrane for gas separation manufactured thereby, in which water is used as a coagulant for a general polymeric solution and macro pores generated in manufacture of the polymeric membrane for gas separation are controlled through phase transition by immersion precipitation. The method of the present invention includes: a step of dissolving a polymer in a solvent to prepare a polymer solution; a step of uniformly dissolving a predetermined amount of LiBr in the polymeric solution to prepare a coating composition, a step of coating a surface of a support body with the coating composition; a step of immersing and precipitating the polymer coated on the support body using water as the coagulant to transit a phase of the coated polymer. [Reference numerals] (S100) Step of issolving a polymer in a solvent to prepare a polymer solution; (S200) Step of uniformly dissolving a predetermined amount of LiBr in the polymer solution to prepare a coating composition; (S300) Step of coating a surface of a support body with the coating composition; (S400) Step of immersing and precipitating the polymer coated on the support body using water as the coagulant to transit a phase of the coated polymer
