Abstract
An inkjet printhead includes an oleophobic membrane arranged at a location that allows the oleophobic membrane to simultaneously vent air from an ink flow channel of the printhead and to retain ink within the ink flow channel. The oleophobic membrane includes a metal structure having a nanostructured surface and low-surface energy coating disposed on the metal structure.
