Abstract: The invention relates to a method for the dispersion of synthetic or natural nanoparticles and nanocomposite materials and to the use thereof in different sectors including those of ceramics, coatings, polymers, construction, paints, catalysis, pharmaceuticals and powdered materials in general.

Abstract: The process is characterised in that it comprises at least one sol-gel layer with a maximum thickness of 800 nm, where said sol-gel layer comprises nanoparticles with a laminar crystal structure, and where each sol-gel layer is obtained from a silicon alkoxide solution; preparation of a dispersion that comprises at least one type of particles with a spherical, fibrillar or laminar morphology, and a laminar crystal structure, wherein at least one of the dimensions, thickness or diameter, of said particles is less than 400 nm; addition of the dispersion prepared to the solution; deposition of the suspension on said substrate; thermal treatment of the substrate; and, in the case of multilayer coatings, optionally, the addition of high-dimensional particles and repetition of the steps, provided that the thermal treatment of the last layer, or outer layer, is performed at a temperature equal to or greater than that of the preceding layer. The invention also relates to the sol-gel coating thus obtained.
