Using imprinted particle structure
View Patent ↗A method of using a multi-layer biocidal structure includes providing a multi-layer biocidal structure having a support and a structured bi-layer on or over the support. The structured bi-layer includes a first cured layer on or over the support and a second layer in a spatial relationship to 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 layer. The multi-layer biocidal structure is located on a surface.
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 the support, the structured bi-layer including a first cured layer on the support, an exposed second layer on and in continuous contact with 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 layer and multiple biocidal particles located only in the second layer; and
providing the multi-layer biocidal structure on a surface.
2. The method of claim 1 , further including providing another second layer over the support.
3. 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 layer in a spatial relationship to the first cured layer on a side of the first cured layer opposite the support, the structured bi-layer having at least one depth greater than the thickness of the second layer and multiple biocidal particles located only in the second layer;
providing the multi-layer biocidal structure on a surface; and
removing at least a portion of the second layer and locating another second 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 cured layer and second layer.
15. The method of claim 1 , further including heating the first cured layer and second layer 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 layer to expose at least a portion of the surface of at least one of the particles.
18. 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 layer in a spatial relationship to the first cured layer on a side of the first cured layer opposite the support, the structured bi-layer having at least one depth greater than the thickness of the second layer and multiple biocidal particles located only in the second layer;
providing the multi-layer biocidal structure on a surface; and
etching, plasma etching, reactive plasma etching, ion etching, or sandblasting the first cured layer or the second layer.
19. The method of claim 1 , further including locating another second layer over the surface.
