THIN-FILM MATERIAL THAT CONTAINS FUNCTIONAL COMPONENTS AND METHOD OF PREPARATION OF THIN-FILM MATERIAL THAT CONTAINS FUNCTIONAL COMPONENTS Russian patent published in 2008 - IPC C08J5/18 B01J16/00 B01J13/10 B82B1/00 B01J13/02 B01J19/00 C08K13/02 

FIELD: technological processes.

SUBSTANCE: invention may be used for preparation of new thin-film composite polymer materials and coatings, which are used in sensor, analytical, diagnostic and other devices, systems of atmosphere and hydrosphere condition forecasting and others. Thin-film material that contains functional components and molecules of polyelectrolites, is formed on the surface of base and is made in the form of layer or layers of poly-ionic complexes of functional components, which are connected to layer or layers of polyelectrolites, at that the quantity of functional components in poly-ionic complex more than 1.Functional components are colloidal particles. Method of preparation of thin-film material consists in performance of procedure of alternating successive layer adsorption of components from water phase on the base. At that beforehand in water phase poly-ionic complexes are formed, which include the molecules of polycations or polycation, polyanions or polyanion and functional components in the quantity of more than 1, creating stochiometric surplus of cation or anion groups of polyelectrolites and functional components and providing difference from zero of summary electrostatic charge of cation and anion groups of such complexes.

EFFECT: ecological safety and possibility of technological process automation.
