This invention relates to method and system for forming a film. The method including providing a trough containing water defining an air-water interface between air and the water; providing a solution containing a material of interest; and electrospraying the solution onto the air-water interface of water to form a film of the material of interest at the air-water interface. The system includes a trough containing water defining an air-water interface between air and the water; and means for spreading a solution containing a material of interest onto the air-water interface of water by electrospray, to form a film of the material of interest at the air-water interface. The spreading means comprises an electrospraying device.
