The present invention relates to a composite separation membrane including a graphene oxide coating layer. The composite separation membrane of the present invention has both high carbon dioxide permeability and high selectivity for carbon dioxide over nitrogen, hydrogen or methane gas, is free of surface defects, and exhibits remarkably increased selectivity for carbon dioxide over other gases (hydrogen, nitrogen, methane, etc.) without any change in carbon dioxide permeability, particularly even when exposed to water. Due to these advantages, the composite separation membrane of the present invention can be applied to industrial fields involving carbon dioxide separation and recovery processes. The present invention also relates to a method for manufacturing the composite separation membrane.
