PROCESS FOR MANUFACTURING SUPER-OIL-REPELLENT AND SUPER-WATER-REPELLENT NANOFILAMENT COATINGS FOR STEEL MATERIALS

Abstract

The useful solution refers to a process for fabricating super-oil-repellent and super-water-repellent nanofiber coatings for steel materials to prevent wax deposition in oil pipelines, including the following steps: polishing the steel surface; electroplating zinc onto the steel surface; creating a nano-structured ZnO layer on the zinc-coated steel surface by heating the steel in a furnace at a temperature between 150 and 250°C; treating the steel surface with UV / O3; treating the resulting steel surface in a mixture containing methyl trichlorosilamine, HCl solution, and toluene solvent; and further treating the steel surface with UV / O3. The steel material surface was then treated with a mixture of 1H,IH^H^H-peridoxyltriethoxysilane and hexane, and the resulting steel material surface was washed three times with toluene, followed by three times with ethanol, and dried in a stream of nitrogen gas.
