METHOD OF PREPARING COATINGS AND FILMS UTILIZING ORGANO-INORGANIC NANOCOMPOSITE MATERIALS BASED ON FILM-FORMING ORGANIC POLYMERS WITH GRAFTED OLIGOSILOXANE CHAINS Russian patent published in 2008 - IPC C09D183/10 C03C17/30 

FIELD: polymer materials and composites.

SUBSTANCE: method of preparing coatings on the surface of glass, plastics, and free films having elevated surface density of functional groups up to 900 nm² provides for applying, on the surfaces, organo-inorganic nanocomposite material based on composition containing solution of film-forming organic polymers with grafted oligosiloxane chains and alkoxysilanes and/or polymers containing amine, hydrazide, epoxide or carboxyl functional groups, after which applied organo-inorganic composition is dried on the surface. Materials can be used in construction of bio- and chemical sensors, especially in the gene diagnostics area, preparation of gene libraries, performance of chain polymerase reaction on immobilized nucleic acids, and as carriers in nucleotide synthesis.

EFFECT: enlarged assortment of novel multifunctional composites.
