1. A method of making a hydrophobic coating that ejects droplets of a condensate from a substrate under condensing conditions, comprising: depositing a nanostructured coating material on a substrate,
wherein the nanostructured coating material comprises a metal oxide,
wherein the method comprises depositing the nanostructured coating material onto the substrate without the introduction of an electric current, and
wherein a hydrophobic functional layer is coated over the nanostructured coating material.
