Superhydrophobic surfaces, characterized by their extraordinary water-repellent properties, and superhydrophilic surfaces, with excellent oil-repellent behavior, can revolutionize the oil/water separation techniques.

Graphene oxide was synthesized using the modified Hummers' method and then sonicated to obtain micrographene oxide, which was later added during the wet finishing before fat-liquoring. Characterization of the micrographene-leather revealed that graphene was incorporated as a protective layer coating over the collagen fibrils, affecting the physical properties of the finished leather. It was found that small quantities of graphene oxide (0.5%) improved the grain cracking resistance, the tear strength and the cracking resistance of leather. It is postulated that low concentrations promote the diffusion of graphene oxide within the leather.
