A composition of matter is a plurality of solid particles of at least 100 nm to about 10 .mu.m in size having a plurality of nanopores where at least some of the nanopores provide flow through porosity, and the surface of the particles displays a plurality of spaced apart nanostructured features with a contiguous material protruding at the surface and optionally at least one interpenetrating recessing contiguous material. The particles are superhydrophobic when the protruding material is hydrophobic or a hydrophobic coating conforms to the surface of the particle. Articles with superhydrophobic surfaces can be formed by the coating of the particles on a solid substrate.
