Title: Superhydrophobic, diatomaceous earth comprising bandages and method of making the same

Abstract

A bandage comprising a substrate having a first surface with a plurality of superhydrophobic particles attached to the first surface. The plurality of superhydrophobic particles can be porous diatomaceous earth particles having a hydrophobic layer conforming to the surfaces of the DE particles, where the hydrophobic layer is bound to the DE particles. The plurality of attached superhydrophobic particles can render the first surface superhydrophobic, while a second surface opposite the first surface can be hydrophilic or hydrophobic. The substrate can be breathable in order to maintain skin health for the tissue underlying the bandage. The substrate can be selected from porous films, apertured films, textiles, nonwoven materials, impregnated composites thereof, and combinations thereof.
