Abstract: This patent is provided a method for producing a porous polymer film using vanadium oxide nanowires, and a porous polymer film obtained from the method. The method allows control of a uniform pore size and density through a simple process including the steps of: adding an ion exchanger to deionized water to perform acidification and adding a vanadate compound thereto to grow vanadium oxide nanowires by a sol-gel process; mixing the resultant solution of grown nanowires with a polymer solution to provide a mixed solution of nanowires; pouring the mixed solution of nanowires to a mold, followed by drying and curing, to form a film; and etching the resultant film with an etching solution to remove the vanadium oxide nanowires.
