Polyurethane-based and epoxy-based coating compositions are described that provide coatings and adhesives that are clear, amphiphobic and durable. Both water and hexadecane readily slide off these surfaces without leaving a residue. Coatings with thicknesses ranging from about 10 nm to about 10 μm exhibited excellent transmittance properties. Such films exhibited durability against abrasion, ink-resistance, anti-graffiti, anti-fingerprint, and strong adhesion to glass surfaces. The coatings are applicable to electronic devices, fabrics, glass, etc. to prepare optically clear, stain-resistant, and smudge-resistant surfaces.
