Abstract

A method of using a multi-layer biocidal structure includes providing a multi-layer biocidal structure that includes a support and a structured bi-layer on or over the support, the structured bi-layer including a first cured layer on or over the support and a second cured layer on or over the first cured layer on a side of the first cured layer opposite the support. The structured bi-layer has at least one depth greater than the thickness of the second layer and multiple biocidal particles located only in the second cured layer. The multi-layer biocidal structure is located on a surface.

First claim

The invention claimed is:

1. A method of using a multi-layer biocidal structure, comprising:
providing a multi-layer biocidal structure that includes a support and a structured bi-layer on or over the support, the structured bi-layer including a first cured layer on or over the support, a second cured layer on or over the first cured layer on a side of the first cured layer opposite the support that completely covers the first cured layer, the structured bi-layer including indentations having at least one depth greater than the thickness of the second cured layer and multiple biocidal particles located only in the second cured layer; and
providing the multi-layer biocidal structure on a surface.

2. The method of claim 1 , further including providing another second cured layer over the support.

3. The method of claim 1 , further including removing at least a portion of the second cured layer and locating another second cured layer over the remaining multi-layer biocidal structure.

4. The method of claim 1 , further including replacing the multi-layer biocidal structure on the surface.

5. The method of claim 1 , further including processing the multi-layer biocidal structure on the surface.

6. The method of claim 5 , further including cleaning the multi-layer biocidal structure.

7. The method of claim 6 , wherein cleaning the multi-layer biocidal structure includes abrading the second cured layer.

8. The method of claim 7 , wherein abrading the second cured layer includes removing at least some particles from the second cured layer.

9. The method of claim 8 , wherein abrading the second cured layer includes exposing other particles in the second cured layer.

10. The method of claim 6 , wherein cleaning the multi-layer biocidal structure includes chemically processing the second cured layer.

11. The method of claim 10 , wherein chemically processing the particles includes improving the biocidal efficacy of the particles.

12. The method of claim 10 , wherein chemically processing the particles includes reducing the biocidal efficacy of the particles.

13. The method of claim 1 , further including mechanically peeling the first and second cured layers.

14. The method of claim 1 , further including chemically removing the first and second cured layers.

15. The method of claim 1 , further including heating the first and second cured layers to remove them from the support.

16. The method of claim 1 , further including heating the multi-layer biocidal structure to remove it from the surface.

17. The method of claim 1 , further including removing a portion of the second cured layer to expose at least a portion of the surface of at least one of the particles.

18. The method of claim 1 , further including etching, plasma etching, reactive plasma etching, ion etching, or sandblasting the first cured layer or the second cured layer.

19. The method of claim 1 , further including locating another second cured layer over the surface.
