A method for the preparation of oriented, anisotropic layers of soluble molecular materials on substrates that were not pre-oriented (so-called zone casting) is presented. The method consists in casting a suitable solution, continuously supplied by a nozzle, onto a moving substrate. Solvent evaporation takes place from the surface of the meniscus formed between a special flat nozzle and the substrate. Due to a gradient of the solute concentration, its solidification proceeds in a narrow zone under highly anisotropic conditions. The conditions of stationary deposition and the influence of various parameters on the process, such as casting speed, the diffusion coefficient, evaporation rate, are discussed. It is shown that the zone casting can be used to obtain anisotropic layers of many different low-molecular-weight and macromolecular materials.
