Abstract
An illustrative embodiment of a contaminant resistant structure includes a substrate having a substrate surface, at least one contaminant resistant material provided on the substrate surface and a hydrophobic or oleophobic, and alternatively, a hydrophilic or oleophilic material provided on at least a portion of the substrate surface.
Claims13
A structure, comprising:
- spaced protrusions between which recesses are defined;
- a biocidal material disposed in the recesses;
- and
- a relatively hydrophobic or oleophobic material compared to the biocidal material disposed on the protrusions, wherein the hydrophobic or oleophobic material is confined to a portion of each of the protrusions.
1 more element
A structure comprising:
- a substrate surface having peaks comprising heights of greater than about 3 microns;
- depressions disposed between the peaks;
- a biocidal material disposed in the depressions;
- and
- an additional material disposed on the peaks, the additional material having an increased hydrophobic property or an increased oleophobic property relative to the biocidal material, wherein the additional material is confined to a portion of each of the peaks.

A structure comprising:
- a substrate surface having peaks comprising heights of greater than about 3 microns;
- depressions disposed between the peaks;
- a biocidal material disposed in the depressions;
- and
- an additional material disposed on the peaks, the additional material having an increased hydrophilic property or an increased oleophilic property relative to the biocidal material, wherein the additional material is confined to a portion of each of the peaks.
2 more elements
A structure, comprising:
- a substrate having a substrate surface including elevated surfaces and depressions extending between the elevated surfaces;
- a biocidal material disposed in the depressions;
- and
- a relatively hydrophobic or oleophobic material compared to the biocidal material disposed on the elevated surfaces, wherein the hydrophobic or oleophobic material is confined to a portion of each of the elevated surfaces.
1 more element
A structure, comprising:
- a substrate having convex portions and depressions disposed between the convex portions;
- a biocidal material disposed in the depressions;
- and
- a relatively hydrophobic or oleophobic material compared to the biocidal material disposed on the convex portions, the hydrophobic or oleophobic material confined to a portion of each of the convex portions.
