Super-hydrophobic bandages and method of making the same

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/m2/day.
