A device for producing polymer films having a predefined spatial structure. The device includes: a linear stage, a platform for a substrate, a cylinder for spreading a polymer solution layer over the substrate to deposit a polymer film onto the substrate, a cylinder height adjustment system, a control system for adjusting a height and tilt of the cylinder in relation to the substrate, a controllable voltage source, one or more metallic electrodes fixed onto the cylinder. The substrate onto which the polymer film is deposited is conductive for electric current. Electric voltage from the controllable voltage source is applied between the metallic electrode and the substrate during deposition of the polymer film onto the substrate.
