Abstract: The present invention relates to a plasma film for airflow control wherein an upper electrode and a lower electrode are asymmetrically attached on the top and underside of a base film to generate plasma therefrom. According to the present invention, the plasma film is formed by attaching the upper and lower electrodes on the top and underside of the base film and then disposed on the surface of an object, thus making it simple to be installed and attached, and since soft dielectrics are used, further, the plasma film can be prefabricated with the appropriate location of the two electrodes to provide optimal performance, thus being freely attached to a desired position. Especially, the plasma film according to the present invention can be just attached even on the gentle curved surface or the surface of the prefabricated object, thus sufficiently achieving the effects of the present invention. Accordingly, if the plasma film is just attached to the surface of an express train or the wing surface of an airplane, air resistance or aerodynamic noise can be reduced, and if it is just attached on the blade surfaces of a wind generator, lift can be increased to improve the generating efficiency.
