A Superhydrophobic Copper Mesh with Microrod Structure for Oil-Water Separation Inspired from Ramee Leaf

It is well known that superhydrophobic surfaces with unitary microstructures (such as the lotus leaf) have better surface mechanical properties than those with binary micro- and nanostructures (such as the ramee leaf). Rodlike unitary structured films are fabricated on copper meshes via a facile and simple chemical vapor corrosion method. Following the surface modification of 1-decanethiol (C10H22S), the resultant films exhibiting superhydrophobicity and superoleophilicity can be applied to separate the oil water mixture.
