From: A Twice Electrochemical-Etching Method to Fabricate Superhydrophobic-Superhydrophilic Patterns for Biomimetic Fog Harvest

Figure 1

Etching process and polarization curve of different surfaces. Schematic illustrations show the etching process (a,b) on superhydrophobic Al area and (c) plasma-treated superhydrophilic area. The screenshots show the etching process (d) on superhydrophobic Al area and (e) plasma-treated superhydrophilic area. (f) Polarization curve of polished Al (P-Al), superhydrophobic Al (S-phobic Al) and plasma-treated superhydrophilic Al (PTS-philic Al), the electrolyte was 1 wt% NaCl aqueous solution.
