Abstract Here we report initial findings in the development of a novel system that allows facile hydrophilic/hydrophobic patterning of a polymer surface with only a two‐step process, involving a fluoroalkylsiloxane (FASx) surface functionalization followed by ion implantation treatment. As the FASx functionalization and ion implantation can be applied to other substrates and the resulting hydrophilicity/hydrophobicity is dependent on the FASx chemistry, this system can likely be applied to any substrate to achieve the same hydrophilic/hydrophobic pattern with similar properties. The way in which water interacts with surfaces has an impact on many different industries, for example those involving food processing and heat exchange, and so the ability to control this interaction and determine the wetting behavior of a surface allows for the development of intelligent interfaces to meet specific operational challenges and improve the efficiency and functionality of such surfaces. Compared to uniform surface properties, the design of a surface with particular areas of hydrophilicity and areas of hydrophobicity allows for greater control of the wetting behavior and of the directional flow of water across the surface.
