Vapor-Gas Deposition of Polymer Coatings on Metals and Mineral Carriers

Abstract

In modern medicine and biotechnology, metal frames and mineral carriers modified with polymer coatings are widely used. In most cases, during polymerization, hydrolytically stable bonds between the polymer and the carrier are not formed on the surface, and the modifying layer is retained on the surface due to adsorption forces or geometric factors.

Vapor–Gas Deposition of Polymer Coatings on Metals from Azeotropic Solutions of Organosilanes

“…Compounds containing a carboxyl group of atoms form strong chemical bonds with hydroxylated surfaces of light metals (Al, Mg) as a result of the condensation reaction of acid protons and hydroxyl groups on the metal's surface [10,11]. Volatile polymer-type corrosion inhibitors (VCIP) based on organosilanes can form a polymer coating on the surface of any metals [12][13][14] and mineral substrates with the formation of strong chemical bonds. Most VCIA compounds have low partial pressures at deposition temperatures of 10 −7 -10 −5 , which significantly reduces the rate of inhibitor deposition.…”
