Patent ID: 8685348

Claim:
A nanowire structural element with a hollow chamber-like structure, which includes: an array of numerous nanowires standing next to each other, and two spaced cover layers, wherein the nanowires extend perpendicularly between the two cover layers and the nanowires are integrally joined at their first ends to the first cover layer and at their second ends to the second cover layer such that the nanowires firmly connect the two cover layers to each other and define the space between the two cover layers, wherein interconnected open spaces exist between the nanowires, such that a stable and freestanding sandwich-like nanostructure contained on two sides by cover layers and permeated with numerous nanowires in a column-manner and a two-dimensionally open cell hollow chamber-like structure is defined in the plane parallel to the cover layers in such a manner that between the two cover layers a fluid can be fed through the two-dimensional open cell hollow chamber-like structure, wherein the nanowires grow caps, wherein the caps have at least partially merged together with each other and the merged caps form a first partial layer of the second cover layer and wherein the second cover layer contains a second partial layer on top of the first partial layer formed by the caps which have merged together.
