The present invention relates to a method for producing a free-standing polymer film having micropores by a simple and economical method, and more particularly, to a method for producing a free standing polymer film, comprising: A) forming a thin film of a water- B) forming a hydrophobic polymer thin film on the water-soluble polymer thin film; C) treating the substrate having the polymer thin film formed thereon with a mixed solution of a solvent and an alcohol of C1-C3; and drying the substrate; And D) separating the hydrophobic polymer thin film from the substrate by immersing the dried substrate in water to dissolve the water soluble polymer thin film, thereby forming a free-standing polymer film having micropores . |
