Abstract
A composition configured to create a superhydrophobic surface includes a fluorinated hydrophobic component dispersible in an aqueous dispersion; cellulosic elements of a size ranging from 100 nm to 100 μm; and water. The hydrophobic component is selected from the group consisting of fluorinated polymers, perfluorinated polymers, and mixtures thereof; and the cellulosic elements are micro- and nano-fibrillated cellulose. A disposable absorbent article includes a substrate having a surface, the surface including a composition including a fluorinated hydrophobic component dispersible in an aqueous dispersion; cellulosic elements of a size ranging from 100 nm to 100 μm; and water, wherein the surface exhibits a contact angle greater than 150 degrees.
