Abstract Biological features such as the bumps on the back of desert beetles and the spikes of cacti enable the
directional transport of water droplets, creating conditions for their survival in nature. Inspired by the
interesting natural phenomenon, a novel design of nanopillared surface with a gradient density of structural
pillar matrix covered by a monolayer graphene is proposed to realize ultrafast self-driving of water droplets.
The droplet can move spontaneously at ultrahigh speed of 75.7 m/s (272.52 km/h) from sparsest to densest
regions of pillars while a wettability gradient is created by the gradient distribution… More >
