Hierarchical polymeric textures via solvent-induced phase transformation: A single-step production of large-area superhydrophobic surfaces

► A single-step preparation of supherhydrophobic surface can be easily scaled up. ► A superhydrophobic structure is formed during solvent-induced crystallization. ► The hierarchical texture consists of microscale spherulites and nanofibrils. ► The texture mimics the exceptional anti-wetting behavior of natural surfaces.
