Abstract
Provided herein are articles including repellent coatings, as well as methods of making as using these articles. The articles can comprise a substrate and a repellent coating disposed on a surface of the substrate. The repellant coating can comprise hydrophobic particles dispersed within a polymer binder. The hydrophobic particles can be aggregated within the polymer binder, thereby forming a multiplicity of re-entrant structures embedded within and protruding from the polymer binder. The repellent coatings, and by extension the articles described herein, can exhibit selective wetting properties (e.g., superhydrophilicty/super-oleophobicity, or super-hydrophobicity/superoleophilicity).
