Abstract
The invention relates to a stamp comprising a nanostructure for introducing and/or applying nanostructures into/onto components as well as a device and a method for producing said stamp. The inventive stamp is provided with a rigid support for the nanostamping structure while the nanostamping structure is joined to the support.

Stamp (2) with a nanostamping structure (3) for the introduction and/or application of nanostructures into/on components, wherein the stamp (2) comprises a rigid support (7) for the nanostamping structure (3) and the nanostamping structure (3) is joined to the support (7), and wherein the nanostamping structure (3) is formed from raised structures (3e) and depressions (3v) adjacent to the raised structures (3e), characterised in that the depressions (3v) are formed extending predominantly up to the rigid support (7).
Stamp according to one of the preceding claims, characterised in that the stamp (2) comprises adjustment means (39).
Device for the production of a stamp (2) with a nanostamping structure (3), for the introduction and/or application of nanostructures into/on components wherein the device (1) includes the following structural parts:
- a receiving means (5) for receiving a rigid support (7);
- at least one master stamp (17) with a nanostructure surface (18), movable relative to the rigid support (7);
- at least one application means (11) for applying a flowable, hardenable polymer, in particular an elastomer, preferably a siloxane and specifically polymer(dimethylsiloxane) (PDMS) (12) to the support (7) and/or to the master stamp (17);
- raised structures (3e) as well as depressions (3v) adjacent to the raised structures (3e) which can be applied via the correspondingly configured nanostructure surface (18) by means of the device, characterised in that the nanostructure surface (18) is designed so that it can be driven directly up to the rigid support (7).
Method for producing a stamp (2) with a nanostamping structure (3) for the introduction and/or application of nanostructures into/on components, the method comprises the following process steps:
- application of a flowable, hardenable polymer, in particular an elastomer, preferably a siloxane, specifically poly(dimethylsiloxane) (PDMS) (12) to a rigid support (7) and/or to a master stamp (17) with a nanostructure surface (18);
- reducing the distance between the master stamp (17) and the rigid support (7) and thereby introducing the nanostructure of the master stamp (17) into the flowable polymer (12) to produce a nanostamping structure (3) with raised structures (3e) and depressions (3v) adjacent to the raised structures (3e), until there is an at least partial contacting of the master stamp (17) with the rigid support (7);
- hardening the polymer (12).
