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 includes a first cured layer including dispersed multiple biocidal particles 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 multiple biocidal particles are dispersed within only the first curable layer. The structured bi-layer has at least one depth greater than the thickness of the second 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 bi-layer on or over the support, the bi-layer including a first cured layer on or over the support, the first cured layer including dispersed multiple biocidal particles, a second layer on or over the first cured layer on a side of the first cured layer opposite the support, wherein multiple biocidal particles are dispersed within only the first cured layer, the bi-layer having a structure including indentations in the first cured layer and the second layer, the indentation having at least one depth greater than the thickness of the second layer;
locating the multi-layer biocidal structure on a surface, and
removing at least a portion of the bi-layer and locating another bi-layer over the support.

2. The method of claim 1 , further including locating another bi-layer over the support.

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

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

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

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

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

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

9. The method of claim 1 , further including heating the multi-layer biocidal structure or an adhesive layer between the multi-layer biocidal structure and the surface to remove the multi-layer biocidal structure from the surface.

10. The method of claim 1 , further including locating another bi-layer over the surface.

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

12. The method of claim 11 , further including cleaning the multi-layer biocidal structure.

13. The method of claim 12 , wherein cleaning the multi-layer biocidal structure includes abrading the second layer.

14. The method of claim 13 , wherein abrading the second layer includes exposing other particles in the first cured layer.

15. The method of claim 12 , wherein cleaning the multi-layer biocidal structure includes chemically processing the second layer.

16. The method of claim 15 , wherein chemically processing the second layer includes improving the biocidal efficacy of the particles.
