Annenkov V.V., Danilovtseva E.N., Filina E.A., Annenkova N.V., Denikina N.N., Belikov S.I. 2008. Method of preparing coatings and films utilizing organo-inorganic nanocomposite materials based on film-forming organic polymers with grafted oligosiloxane chains. Patent RU 2318852.
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 filmforming 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.
