NOVELTY - Preparing graphene-based superhydrophobic low-carbon steel involves polishing low-carbon steel first with 60 mesh, 120 mesh, 320 mesh, 600 mesh, and 1200 mesh sandpaper, respectively to remove impurities and oxides on the surface, ultrasonically cleaning with absolute ethanol and acetone for 10 minutes to remove organic matter, and then drying with nitrogen, where electrolyte formula comprises graphene oxide 15%-30%, linolenic acid 15%-30%, no Water ethanol is 40%-70%, the sum of the percentages of each component is 100%. USE - Method for preparing graphene-based superhydrophobic low-carbon steel. ADVANTAGE - The method enables to prepare graphene-based superhydrophobic low-carbon steel that gives full play to the lamellar barrier function of graphene, and the corrosion inhibition efficiency is more than 99%, and has a wide range of industrial application prospects.
