Programmable Droplet Bouncing on Bionic Functional Surfaces for Continuous Electricity Generation

“…[12][13][14][15][16] The bouncing status and velocity of the droplet are strongly influenced by the hydrophobic microstructures on these surfaces, thus enabling their numerous potential applications in water transportation, [17][18][19] selfcleaning, [20][21][22] anti-icing, [23][24][25] etc. [26][27][28][29][30] In general, most hydrophobic micro/nanostructured surfaces, such as lotus leaf, [31][32] feathers, [33] butterfly wings, [34,35] and rose petals, [36,37] can achieve a static water contact angle (CA) larger than 150°, indicating that water droplets can bounce on such superhydrophobic surfaces. [38][39][40] For example, Liu et al [41] studied the pancake bouncing of a water droplet on superhydrophobic surfaces and achieved rapid detachment between the droplets and surfaces over a wide range of bouncing velocities.…”
