Water-repellent film, film formation method, nozzle plate, ink-jet head, and ink-jet recording device
Abstract:
Disclosed is a water-repellent film 102 including a substrate 100, and a water-repellent organic material provided on the substrate 100, in which a plurality of regions having different concentrations of the water-repellent organic material are formed, and each of the regions having different concentrations continuously exists in a film thickness direction from a boundary surface with respect to the substrate to a surface of the water-repellent film. Preferably, in the regions having different concentrations, a region having a relatively higher concentration 102a is formed into the shape of a column, and a region having a relatively lower concentration 102b than that of the columnar region exists around the columnar region.
