Abstract

•Stainless steel meshes (SSM) with bipolar wettability were successfully fabricated.•Oil (low density)-water mixtures can be separated by highly-hydrophilic SSM.•Oil (high density)-water mixtures can be separated by hydrophobic SSM.•Modified SSM of small pore size can present effective oil-water separation.•Hydrophobic SSM can be used to collect oil from oil-contaminated water.
