Preparation of coatings containing at least one in-plane oriented layer of anisotropic shaped objects

摘要

The subject matter of the present invention concerns the preparation of a coated solid surface wherein the coating contains at least one in-plane oriented layer of anisotropic shaped objects through a specific spraying method, and the device enabling this method. The method includes the preparation of a solution, suspension or dispersion of interacting objects, and the spraying of the solution, suspension or dispersion on a solid surface with an angle preferably inferior to 30°, with respect to the plane formed by the solid surface to be coated, and a droplet speed superior to 0.1 meters per second.
