Functionalization of graphene oxide coatings with phosphorus atoms and their corrosion resistance in sodium chloride environment
Abstrakt
In this work, we compared corrosion resistance of graphene oxide, and phosphorus functionalized reduced graphene oxide coatings obtained as a result of electrophoretic deposition on the copper substrate. Doping graphene oxide with phosphorus atoms was performed by a hydrothermal method in the presence of different amounts of phosphoric acid. Structural studies confirmed the insertion of phosphorus atoms into the graphene oxide structure. FTIR spectra showed peaks at 1020 cm−1 and 1131–1450 cm−1 which can be assigned to phosphorus groups. XPS analysis indicated that phosphorus atoms were inserted in an amount of around 5%. The stable and uniform suspension of functionalized graphene precursors of coatings allowed electrodeposition. These coatings show good protective properties due to hydrophobic and intact surfaces without significant damages.
