The present invention relates to a gingerol derivative having inhibitory activity against biofilm formation and a pharmaceutical composition for preventing or treating infections caused by biofilms including the gingerol derivative as an active ingredient. The gingerol derivative of the present invention exhibits significantly improved binding affinity for LasR and inhibitory activity against biofilm formation. Therefore, the gingerol derivative of the present invention can act on various membrane surfaces where biofilms tend to form and can effectively inhibit the formation of the corresponding biofilms. In addition, the use of the pharmaceutical composition according to the present invention can fundamentally prevent or treat a variety of infections caused by biofilms due to the presence of the gingerol derivative in the pharmaceutical composition.

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.
