(a) Schematic illustration of a solid-liquid-vapor interface of the conventional hydrophobic separator structure for water. (d) Water contact angle measurement and (c) photograph of large-area wetting feature on the conventional hydrophobic separator. For visualization, Co(NO3)2·6H2O dissolved water was used.
