Heterostructures: Underwater Mechanically Robust Oil-Repellent Materials: Combining Conflicting Properties Using a Heterostructure (Adv. Mater. 11/2018)

In article number 1706634, Liping Heng and co-workers present a new strategy for oil-repellent materials based on a combination of conflicting properties using a heterostructure. An outer hydrophilic poly(acrylic acid) (PAA) hydrogel coating prevents the adhesion of various oils to the material underwater. The inner hydrophobic layer microstructure endows the material with excellent mechanical properties underwater.
