MacDiarmid Institute, Jilin University, Changchun 130012, PR China GR APHICAL A BSTRACT ARTICLE I NFO ABSTRACT Keywords: Electrospun nanoﬁbrous membranes with a large number of nano-sized micropore possess excellent potential in Electrospinning the applications of oil harvesting and oil/water separation. In this study, a green and simple approach was Electroless plating successfully applied to fabricate superhydrophobic and superoleophilic nanoﬁbrous mats through the combi- Cu nanocluster nation of electrospinning and electroless plating techniques. We designed hierarchical structure by immobilizing Superhydrophobic Cu nanocluster on the surfaces of Ag seeds loaded electrospun polyacrylonitrile (PAN) nanoﬁbers and followed Oil/water separation with a surface modiﬁcation process by n-hexadecyl mercaptan immersion. The fabricated superhydrophobic Oil harvesting PAN nanoﬁbrous membranes showed the wetting property with a water contact angle (WCA) of 154.6° and a sliding angle lower than 8.0°. Owing to the super hydrophobicity and their high porosity
