Abstract
A superhydrophobic non-fluorinated composition includes a hydrophobic component free of fluorine; a filler particle; and water, wherein the composition is at a pH greater than 7, and wherein the hydrophobic component is in an aqueous dispersion. The superhydrophobic non-fluorinated composition alternatively includes a hydrophobic polymer free of fluorine; an exfoliated graphite filler particle including acid functional groups; water; and a stabilizing compound, wherein the composition is at a pH greater than 7, and wherein the hydrophobic polymer is in an aqueous dispersion. The superhydrophobic non-fluorinated composition alternatively includes a hydrophobic component free of fluorine; a filler particle including an acid functional group; and water, wherein the composition is at a pH greater than 7, and wherein the hydrophobic component is in an aqueous dispersion.
