In the last two decades, materials of extreme wetting properties (MEWP) have received significant attention, as they offer new perspectives providing numerous potential applications. Biomimetics, super-hydrophobic/oleophobic and water-/oil-repellent surfaces can be used, for instance, in automobiles; ships and aircrafts; microelectronics; textiles; biomedical devices and implants; devices in renewable energy systems; constructions and buildings; and in other applications relevant to self–cleaning, friction reduction, oil–water separation, water harvesting and desalination, drug delivery, anti-icing, anti-corrosion, and anti-bacteria methods.
Despite the large scientific progress on MEWP, there are still some obstacles that have to be solved to make these materials available for real life applications. For example, the durability of the surfaces of MEWP is clearly a main obstacle. Recent advances on the production strategies, including methods and materials, of MEWP showed that the durability and sustainability obstacles can be addressed. Recent studies suggest that metals, semiconductors, ceramics, polymers (natural and synthetic), and modern materials such as nanocomposites and graphene can be tuned to MEWP following cost-effective and eco-friendly methods and materials.

Abstract: The mixture of insoluble organic oil and water seriously affects the human health and the environmental safety. It is important and significant to develop an efficient material to remove oil from water. In this work, we report a superhydrophobic Cu2O mesh that can effectively separate oil and water. The superhydrophobic Cu2O surface was fabricated by facile chemical reaction based on the copper mesh without any low surface reagents treatment. With the advantages of simple operation, short reaction time and low cost, the as-synthesized superhydrophobic Cu2O mesh has excellent oil-water selectivity for many insoluble organic solvents. In addition, it could be reused for oil-water separation with the high separation ability of above 90%, which demonstrated excellent durability and reusability. It is expected that this fabrication technique will have great application prospects in the field of oil-water separation.
