Definitions
- the invention relates to a method by which the surfaces of arbitrary bodies can be provided with subordinate microstructures or nanostructures and micro- and / or nano-sized apertured films can be produced.
- microstructures or nanostructures are becoming increasingly important, as their properties differ significantly from those of unstructured surfaces. So z. B. by topical nanostructures the wettability of surfaces greatly reduced (lotus effect) or increased by subordinate structures (oil pockets of stamping tools). Furthermore, the flow resistance of surfaces can be reduced (riblet surfaces), the geometric (eg in heat exchangers) or reactive surface (eg electrodes of fuel cells) increases and the optical behavior of the surfaces (eg Application of microlenses, microprisms).
- Archetypes are typically made by lasering or micromilling the requisite microstructures or nanostructures into the surface of a blank. Both lasing and micro milling are associated with considerable time and equipment.
- a further disadvantage is that the shapes of the recesses introduced into the surface during lasering can not be practically (always funnel-shaped) and micro-milling made only slightly (rotationally symmetrical).
- DE 10 2007 047 162 A1 describes a method for the production of microstructures or nanostructures formed from flocks of metallic columns, in which a template which has a family of through-holes is placed on a carrier with an electrically conductive surface and then electrodeposited on the assembly. As a result, the columnar metal structures are applied to the support in the region of the through holes.

- the surface to be embossed and the tool are tilted towards each other, that is, they include a usually small angle of less than 10 ° with each other.

- nanomaterials which usually have a higher hardness than the corresponding starting materials, are better suited for impressing depressions than their starting materials.

- the method according to the invention can be used either for directly signing objects with codes or for embossing codes in production tools, master tools or tool inserts. If standard embossing tools are used for embossing the depressions, then the forgery-proofness of the codes is achieved via the characteristic arrangement of the depressions. For example, very fine codes are generated that are invisible to the naked eye. To further increase the security against counterfeiting, embossing tools with points, defined radii or sharp edges can be used, which have a characteristic shape and / or surface structure, which makes it possible to identify all recesses produced by this tip.

- the stamping material may be a material having a high reflectance (with respect to a given wavelength of light), wherein optical reading of a corresponding code may be accomplished by scanning the signed object with light and detecting the positioning of the reflective areas by means of an optical sensor.
- the stamping material may be made of a material having a low reflectivity (with respect to a given predetermined wavelength of light), and the reading and detection of the code also by means of an optical sensor can take place.
- embossing codes Another interesting use case for embossing codes is the labeling of textiles or paper. To generate the codes, either recesses are embossed into the individual threads / fibers or individual (fine) threads / fibers are severed in a defined manner.
- the marking of substances by embossing depressions is also non-destructive. Since the fabric-embossed patches may no longer be detectable after multiple washes, the method is useful e.g. for marking unprocessed textile fabrics (fabric bales).
- codes that cut through individual threads of textiles are not non-destructive, they can also be used to label processed textile fabrics, ie garments, since they can not be rendered unrecognizable by cleaning or washing processes. If, as is readily possible with the method, only very fine threads are severed and the distances between the severed threads are chosen to be large, the mechanical load-bearing capacity of the textiles at the location of the applied code is virtually unaffected. adversely.
- the codes are either applied directly to the textiles or, as described above, spinning, weaving or winding tools are produced with top structures which emboss codes during the processing of the textiles and / or codes by cutting individual threads produce the textiles to be labeled.
- a further modification consists in applying a structuring on the (usually mechanically) stressed surfaces with the method according to the invention, which enables a measurement of the friction occurring on the surface and of the wear to which this surface is exposed.
- Another use of the embodiment of the method with simultaneous stamping of stamped material is e.g. in the production of Peltier elements with very small and very many individual Peltier elements of different Peltier material pairs (eg corresponding n- and p-doped semiconductor regions) and their ohmic connections (eg the electrical connecting lines of such n- and p-doped semiconductor regions), where eg such oppositely doped semiconductor regions can be introduced into respective, spaced apart embossed depressions and these depressions are electrically connected to one another by means of a recess lined with an electrically conductive material.
