NOVELTY - Preparation of aluminum biomimetic superhydrophobic graphene film involves removing oxide layer of aluminum alloy, processing surface of resultant aluminum alloy, soaking copper foil substrate in hydrochloric acid solution, annealing, introducing mixed gas into tubular reactor, placing copper foil substrate in reactor, growing graphene film on substrate, cooling, spin-coating poly(methyl methacrylate) on substrate, curing, etching, covering surface of processed aluminum alloy with composite poly(methyl methacrylate)-graphene film, curing, and removing poly(methyl methacrylate) layer. USE - Preparation of aluminum biomimetic superhydrophobic graphene film (claimed). ADVANTAGE - The method enables preparation of aluminum biomimetic superhydrophobic graphene film with excellent durability, reproducibility and stability, at room temperature condition, by simple process. DETAILED DESCRIPTION - Preparation of aluminum biomimetic superhydrophobic graphene film involves removing oxide layer of aluminum alloy, processing surface of resultant aluminum alloy, forming array-type cylindrical convex hull structure, washing surface of a copper foil substrate with ethanol, acetone and distilled water at room temperature, soaking washed substrate in 10-20% hydrochloric acid solution for 5 minutes, washing soaked substrate with water to remove surface oxide layer, drying, annealing at 1000 degrees C for 0.5 hour in oxidation atmosphere, introducing mixed gas containing methane and hydrogen in volume ratio of 1:1 into a tubular reactor at flow rate of 10 mms, placing copper foil substrate in the reactor, growing graphene film on the surface of copper foil substrate at 1030 degrees C, cooling to room temperature, removing copper foil substrate from the reactor, spin-coating poly(methyl methacrylate), curing at 100 degrees C, etching resultant substrate using 200 mg/ml etchant, cleaning with distilled water, covering the surface of processed aluminum alloy with obtained composite poly(methyl methacrylate)-graphene film, curing at 100 degrees C, and removing poly(methyl methacrylate) layer using acetone solution.
