Water‐Proof Protection: Highly Stretchable Superhydrophobic Composite Coating Based on Self‐Adaptive Deformation of Hierarchical Structures (Small 19/2017)

A highly stretchable superhydrophobic surface is prepared by Changyu Tang and co-workers in article number 1602353, through a facile spray-coating of nano-carbon black/polybutadiene elastomeric composite on a rubber substrate. The hierarchical roughness of the resulting composite coating exhibits a self-adaptive deformation behavior and enables the surface to maintain a superhydrophobic property (water contact angle ≈170° and sliding angle <4°) at a stretching strain of up to 1000%.
