Creating superoleophobic surfaces typically involves nanostructuring the surface to introduce roughness and applying a low surface energy coating. The process can be broken down into two main steps: 1. Surface Roughness: This is achieved through various nanofabrication techniques such as etching, lithography, and self-assembly. 2. Chemical Functionalization: The rough surfaces are then coated with low-energy materials like fluoropolymers or siloxanes to enhance their oleophobic properties.
