In this paper, a superhydrophobic surface for oil-water separation were fabricated by grafting polymer on 3D hierarchical polydopamine-graphene (PDA-graphene) aerogel modified stainless steel mesh (SSM). The chemical compositions and surface morphology of the as-prepared composite were characterized by HNMR, FTIR and SEM. The results show that polymer/PDA-graphene/SSM exhibits unique interfacial properities, including hierarchically porous structure, large specific surface area, hydrophilicity and oleophobicity, hence it could work as excellent oil-water separation material. Oil-water separation experiments indicate that the average water permeation of the film is 1155 L h-1m-2bar-1, and the separation efficiency is 99.1%, which identifying the excellent performance of polymer/PDA-graphene/SSM.
