Offshore oil-spill has become the most emerging problem in the world. In the current paper, a graphene\/ZnO\/polymer nanocomposite thin film is coated on stainless steel mesh via layer by layer deposition method. The structural characterization of materials is determined by Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). The total petroleum hydrocarbons (TPHs) and separation efficiency have been measured via gas chromatography – flame ionization detector (GC-FID). TPHs are reduced to 2 ppm and separation efficiency of the nanocomposite coated mesh is reached ≥ 99% for the final sample. The nanocomposite coated mesh acts as a promising candidate for the separation of oil- water mixture.<\/p>\r\n","references":"[1]\tCarpenter A. \u201cOil pollution in the north sea: The impact of governance measures on oil pollution over several decades.
