METHOD OF PREPARING THIN-FILM NANOCOMPOSITE COATING ON SOLID-STATE BODY Russian patent published in 2008 - IPC B82B3/00 

FIELD: technological processes.

SUBSTANCE: invention essence: method of preparing thin-film nanocomposite coating includes introduction of solution consisting of nanocomponents and water insoluble compound of amphiphile polyelectrolyte in volatile non-polar dissolvent on the surface of water phase with forming nanocomposite monolayer with further junction of nanocomposite monolayer by the method of Langmuir-Blodgett onto solid-state body with forming a nanocomposite coating on its surface. As water insoluble compound of amphiphile polyelectrolyte alkylated derivatives of amphiphile polycationic or polyanionic compounds are used. At that nanocomponents of single type are used, which differ in their size by not more than 10%, out of the group: clusters, nanocrystals, nanoparticles, nanorods, nanowires, nanotubes, and in the process of forming the nanocomposite monolayer is incubated at the temperature T=16-58°C for the time sufficient for creation of well-ordered nanocomponents structure in monolayer plane.

EFFECT: thin-film nanostructures are characterized with low degree of disruption in nanoparticles localization in coating film.
