Controlled bouncing, evaporation and transport of droplet on liquid-repellent surface (IMAGE)
Caption
A facile and industrially applicable method for fabricating an extreme wettability surface on an Al-based superhydrophobic surface by a composite process of electrochemical mask etching and micro-milling (Figure 1S1). Controlled evaporation of droplets on hydrophilic micropit dot matrix patterns of “HNU” can be achieved by controlling geometry of hydrophilic patterns (Figure 1S2). Controlled bouncing of droplets on the junction of surfaces with different wettability under high temperature (Figure 1S3). Controlled transport of droplets over a wide temperature range with confluence by using Laplace pressure gradients on extremely wettable surfaces was realized (Figure 1S4).
