Abstract
A bioactive coated substrate includes a base substrate, a first interlayer disposed over the base substrate, an outermost bioactive layer disposed on the first interlayer, and a topcoat layer disposed on the outermost bioactive layer. Characteristically, a plurality of microscopic openings extending through the topcoat layer and the outermost bioactive layer expose the first interlayer and the outermost bioactive layer. A method for forming the bioactive coated substrate is also provided.
Claims25
A bioactive coated substrate comprising:
- a base substrate;
- a first interlayer disposed over the base substrate;
- an outermost bioactive layer disposed on the first interlayer;
- and
- a topcoat layer disposed on the outermost bioactive layer, wherein a plurality of microscopic openings extending through the topcoat layer and the outermost bioactive layer to expose the first interlayer and the outermost bioactive layer, the plurality of microscopic openings originating in the first interlayer.
A method of producing a bioactive coated substrate comprising:
- providing a base substrate;
- depositing a first interlayer over the base substrate, the first interlayer having a plurality of macroparticles protruding from a surface of the first interlayer;
- depositing an outermost bioactive layer over the first interlayer, the plurality of macroparticles extending into the outermost bioactive layer;
- depositing a topcoat layer on the outermost bioactive layer, the plurality of macroparticles extending into the topcoat layer;
- and
- removing at least a portion of the plurality of macroparticles to form a plurality of microscopic openings in the topcoat layer.
