Abstract
The invention pertains to methods of obtaining anisotropic crystalline films and to devices for carrying out the methods. A colloidal system with anisometric particles is applied as a film onto the surface of a substrate while the viscosity of the colloidal system is lowered. The particles of the colloidal system with lowered viscosity are oriented and the original viscosity of the colloidal system is restored. The film is then dried. The drying is carried out under controlled conditions. Zones of the dried film may be progressively heated to improve the film characteristics.
