description A superhydrophobic surface includes a substrate treated with a non-fluorinated, water-based composition including a hydrophobic component free of fluorine, a hydrophilic filler particle, wherein the filler particle is a metal oxide nanoparticle, and water, wherein the hydrophobic component is in an aqueous dispersion. Also, a superhydrophobic surface includes a substrate treated with a non-fluorinated composition including a hydrophobic polymer free of fluorine, titanium dioxide nanoparticles as filler, and water. In addition, a superhydrophobic surface includes a substrate treated with a non-fluorinated composition including a hydrophobic polymer free of fluorine, wherein the hydrophobic polymer includes a polyolefin; titanium dioxide nanoparticles as filler, wherein the titanium dioxide nanoparticles are rutile titanium dioxide, anatase titanium dioxide, or a mixture of rutile and anatase titanium dioxide; and water.
