The present invention relates to a method for forming a uniform, extremely thin film on the surface of plastics molded articles, films, sheets, synthetic paper, fibers, metal, and other objects, the film containing an anti-static agent, anti-fogging agent, anti-corrosive agent, mildewproofing agent, and the like. According to the method of the present invention, a homogenous solution or emulsion is prepared by dissolving a surfactant and agents in a solvent such as water with the aid of ultrasonic waves, and the solution is made into aerosol of fine particles by means of cavitation. The aerosol is brought into contact with an object, whereby the fine particles of aerosol are deposited on the object and a thin film of the solution is formed on the surface of the object due to the difference in surface tension between the surfactant and the object. After evaporation of the solvent, the agents are left on the surface of the object in the form of an extremely thin film. The present invention also relates to apparatuses for producing such aerosol, selecting aerosol particles, and bringing the aerosol into contact with the surface of an object.
