METHOD OF ENDOWING MATERIALS WITH HYDROPHILIC PROPERTIES USING ORGANOSILOXANE COATING WITH NITRILOTRIMETHYLENE PHOSPHONIC ACID

摘要

FIELD: chemistry.SUBSTANCE: to endow various materials with hydrophilic properties, a modifier is deposited on the surface of said materials. A coating is formed by successively depositing aqueous solution of an oligo(aminopropyl)ethoxysilane of a general formula shown on fig 1, and subsequently depositing aqueous solution of nitrilotrimethylene phosphonic acid of a general formula shown on fig 2. After deposition, each solution is dried on air and heat treated.EFFECT: invention enables to endow various materials with improved hydrophilic properties.8 dwg, 6 ex
