Patent ID: 8193406

Claim:
A bandage comprising: a substrate having a top surface, and a hydrophilic bottom surface opposed to the top surface; a plurality of particles, ranging in size from about 100 nanometers to about 10 micrometers; and a dressing attached to the hydrophilic bottom surface, wherein the plurality of particles are formed from an interpenetrating blend having at least one protrusive phase, wherein each of the plurality of particles has a plurality of spaced apart nanostructures defining an external boundary of each particle, wherein a plurality of the spaced apart nanostructures are coated with a hydrophobic coating material that renders the plurality of particles superhydrophobic, wherein each of the plurality of particles has a flow through porosity provided by a plurality of nanopores having connectivity through each particle, wherein the plurality of particles are bound to the top surface with a binder, wherein the substrate separates the superhydrophobic particles from the dressing, wherein the binder does not diminish a topography of the spaced apart nanostructures, thereby allowing the plurality of particles to render the top surface superhydrophobic, wherein the bandage has a water vapor transmission rate, measured according to ASTM Standard E96-80, of at least 50 g/m 2 /day.
