Abstract:
1. Method for the continuous deposition on a substrate of a thin homogeneous layer of a product obtained from at least two reactive partners, characterised in that it involves the: simultaneous continuous spraying, or alternate continuous spraying of two reactive partners of inorganic nature, on said substrate, using separate sprayers, of at least two liquids each containing one of the reactive partners or a mixture thereof, such that clouds of droplets are produced containing droplets of micro and nanometric size which interact together mainly at the level of a liquid film of controlled thickness comprised between 0.1 μm and 100 μm that forms on contact with a free surface of the substrate, and wherein the thickness of said thin homogeneous layer of product, formed from said liquid film, is mainly controlled by the duration of said continuous spraying, except where two reactive partners are of polymer nature, interact by electrostatic interactions, and are deposited by simultaneous spraying; wherein the sprayers comprise nozzles arranged so that spraying jets of the liquids from the nozzles arrive at the surface of the substrate along a direction essentially orthogonal with respect to the latter.
