Patent ID: 8870839

Claim:
A disposable treatment article for contacting a bodily surface and improving the contamination resistance of the bodily surface, the disposable treatment article comprising: one or more substrates comprising an activatable nanostructure forming material comprising one of a crushable nanoporous material or an aerogel, having a surface and wherein prior to activation, the nanostructure forming material has substantially no nanostructures on the nanostructure forming material's surface, the nanostructure forming material providing hydrophobic nanostructures to the bodily surface when the activatable nanostructure forming material is activated by activation means selected from the group consisting of: application of a crushing force, application of a shear force, application of a crushing pressure, and combinations thereof, and at least a portion of the nanostructure forming material is deposited on the bodily surface, the hydrophobic nanostructures comprising a plurality of nanoscale elevations and depressions, wherein the nanostructure forming material when activated and applied to the bodily surface reduces the adherence of a contaminant to the bodily surface; wherein the nanostructure forming material comprises particles having an average particle size from 500 micrometers to 1 mm.
