Abstract

The invention relates to a self-cleaning self-regenerating surface structure and/or a self-cleaning self-regenerating coating. For improving the cleaning function, the invention proposes a self-regenerating surface structure, especially coating, comprising biocatalytic and/or anti-icing molecules on an exposed surface of said surface structure, especially coating, and biocatalytic and/or anti-icing molecules embedded or contained in said surface structure, especially coating. Further, the invention relates to an object provided with such surface structure or coating and a method for producing the same.

First claim

The invention claimed is:

1. A self-regenerating surface structure comprising at least one of molecules from the group consisting of biocatalytic molecules and anti-icing molecules, said at least one of said molecules located on an exposed surface of said surface structure and at least one of said molecules from said group are embedded or contained in said surface structure so as to form a self-regenerating surface structure.

2. The surface structure according to claim 1 , wherein the molecules from the group are contained in an inner layer beneath the surface.

3. The surface structure according to claim 2 , wherein an outer layer covers at least one inner layer and both said layers contain molecules from the group.

4. The surface structure according to claim 1 , wherein the molecules from the group are at least one of adhered to or contained in a carrier material.

5. The surface structure according to claim 4 , wherein the carrier material is present in form of particles embedded in a surface material or coating material or is present as surface material or coating material itself.

6. The surface structure according to claim 5 , wherein the carrier material has at least one of inner channels and cavities containing the molecules from the group.

7. The surface structure according to claim 1 , wherein the structure comprises at least one of μ-channels and μ-pores for at least one of a transport or a storage of non-linked molecules from the group.

8. The surface structure according to claim 1 , wherein the structure comprises a plurality of layers comprising the molecules from the group, said plurality of layers provided by layer-by-layer deposition.

9. The surface structure according to claim 1 , wherein said structure comprises a tree-like structure of the molecules from the group, said tree-like structure immobilized to a depth of the surface structure.

10. The surface structure according to claim 1 , wherein said structure includes fusion proteins.

11. An object having said surface structure according claim 1 .

12. A method for providing a self-regenerating surface structure comprising the steps of:
providing molecules from a group consisting of biocatalytic and anti-icing molecules on said surface structure; and
providing molecules from the group embedded or contained in said surface structure.

13. The method according to claim 12 , including the step of introducing molecules from the group into an inner layer of a surface coating material or surface forming material.

14. The method according to claim 12 , including the step of increasing density of molecules from said group in a surface coating material or surface forming material.

15. The method according to claim 12 , including the step of providing a tree-like structure of the molecules from the group within a surface coating material or surface forming material.

16. The method according to claim 12 , including the step of providing at least one of micro-channels and micro-pores for at least one of transport and storage of the molecules from the group in a surface coating material or surface forming material.

17. The method according to claim 12 , including the step of providing said surface with fusion proteins.

18. The method according to claim 12 , comprises at least one of the following steps:
immobilising the molecules from the group on particles made of a carrier material and introducing the particles into the surface coating material or surface forming material; and
immobilising the molecules from the group on molecules or particles of said carrier material forming the surface coating material or the surface forming material.

19. The method according claim 14 , including the step of providing a multi-layer assembly by deposing a first layer having the molecules from the group and covering the first layer with at least one second layer also having molecules from the group.

20. The method according to claim 14 , including at least one of the following steps:
providing the surface coating material or surface forming material with at least one of micro-channels and micro-pores containing a liquid carrying the molecules from the group;
transporting a liquid carrying the molecules from the through at least one of micro-channels and micro-pores provided in a surface coating material or a surface forming material from an inner region to an outer surface by capillary action or via micro pumps;
combining different molecules from the group to form combined single molecules; and
combining the molecules from the group with a tag promoting an immobilization or enabling a defined immobilization.

21. The surface structure according to claim 1 , wherein the surface structure is a coating.
