ABSTRACT:
Article of manufacture comprising a substrate and a coating layer. The coating layer comprises at least one coating material, and is stably affixed to the substrate to form a stable, coated surface. The coated surface has a texture that mimics the topography of mammalian keratinous tissue and demonstrates at least one physical property representative of mammalian keratinous tissue, selected from the group consisting of a total surface energy of from about 15 mJ/m2to about 50 mJ/m2, a dispersive component of the surface energy of from about 15 mJ/m2to about 50 mJ/m2, a polar component of the total surface energy of from about 1 mJ/m2to about 14 mJ/m2, a zeta-potential at a pH of about 5.0 of from about −40 mV to about 30 mV, and combinations thereof.
