1. A process of preparation of a coated solid surface wherein the coating contains at least one in-plane oriented layer of anisotropic shaped objects, comprising:
a) the preparation of at least one solution, suspension or dispersion of interacting objects, b) the spraying of at least one solution, suspension or dispersion of step a) on a solid surface said spraying is done with:
an angle inferior to 80°, preferably inferior to 30°, with respect to the plane formed by the solid surface to be coated,a droplet speed superior to 0.1 meters per second, in particular wherein the combination of the droplet and gas in movement generates a movement of the newly formed thin layer on the surface of the substrate to be coated, c) previously, simultaneously or subsequently to step b), an optional spraying or application of at least one complementary interacting chemical species, such as an interface and/or cohesion agent, onto the coated and/or uncoated surface,
steps a), b) and/or c) being reproduced as many times as necessary to obtain the desired coating, and d) retrieving the coated solid surface. |
