The invention relates to the technical field of conductive films and in particular to a method for preparing a defogging and defrosting glass film. During manufacturing of a polyvinyl butyral (PVB) film, high-molecule conductive particles are added, so that the PVB film has functions of conducting electricity and heating. The method is suitable for manufacturing conductive films with various shapes and thicknesses, such as the conductive films for heating glass on automobiles, trains, ships, airplanes and buildings. The glass produced by using the method is high in visible light transmissivity, and is stably and uniformly heated, so that the driving safety is improved greatly.
