A method for modifying a surface of a hydrophobic polymer film and surface-modified hydrophobic polymer film are disclosed. The method includes placing a hydrophobic polymer film in a reactor for atmospheric pressure plasma polymerization; supplying a first reaction gas into the reactor to form a physical barrier layer on the hydrophobic polymer film via plasma deposition; and supplying a second reaction gas into the reactor to form a hydrophilic coating layer on the physical barrier layer via plasma deposition. The method enables operation and maintenance of apparatuses and equipment at low cost, and providing efficiency in treatment of large films. Further, the surface-modified hydrophobic polymer film includes a double layer including a physical barrier layer and a hydrophilic coating layer on a polymer film to prevent diffusion of hydrophobic polymer molecules, thereby providing improved surface wettability to the film surface and maintaining hydrophilicity of the film for a long time. |
