FIELD: chemistry.
SUBSTANCE: surface of materials is successively coated with an aqueous or alcohol solution of oligo(aminopropyl)ethoxysiloxane, dried and then heat treated. Further, the modified surface is wetted with an alcohol solution of glycidol, followed by drying and heat treatment. A layer of a modifier which gives the surface of the materials hydrophilic properties is formed on the surface of the materials as a result. The modifier is formed directly on the surface by molecular assembly of organosiloxane coatings with N,N-bis(1,2-dihydroxypropyl)aminoalkyl groups.
EFFECT: invention enables to modify treated materials to obtain a micro- or nano-size coating with different hydrophilic properties on their surfaces.
