Аннотация: Abstract The paper considers the production and use of alumina nanofibrous additives in nanocomposite powder paints. The main component of powder paints are polyester resins with a large number of free carboxyl groups, which are cross-linked with special hardening additives. The introduction of additives into the resin is most effective when their surface is matched in terms of physicochemical properties with the resin material. In order to increase the affinity of the alumina nanofibers with the powder paint matrix, the amphoteric surface of the nanofibers must become acidic. The paper describes a method for the functionalization of alumina nanofibers by successive silanization with aminopropyltriethoxysilane and priming with oxalic acid. The paper described about the compounding of alumina nanofibers leads to increase of the coating strength and an increase in its elasticity. Priming alumina nanofibers by aminopropyltriethoxysilane in toluene leads to its functionalization sufficient to homogenize the nanofibers in the polymer media of the powder paint and improve its product properties. The formation of an amide bond after the final stage of priming of alumina nanofibers in oxalic acid by indirectly method is shown.
