A template based process is used for the production of the nanowire structural element, wherein the nanowires are electrochemically depositioned in the nanopores. The irradiation is carried out at different angles, such that a nanowire network is formed. The hollow chamber-like structure in the nanowire network is established through the dissolving of the template foil and removal of the dissolved template material. The interconnecting of the nanowires provides stability to the nanowire structural element and an electrical connection between the nanowires is created thereby.

Nanowire structural element

The invention concerns the production of segmented nanowires and components having said segmented nanowires. For the production of the nanowire structural element, a template based process is used preferably, wherein the electrochemical deposition of the nanowires in nanopores is carried out. In this manner, numerous nanowires are created in the template foil. For the electrochemical deposition of the nanowires, a reversed pulse procedure with an alternating sequence consisting of cathodic deposition pulses and anodic counter-pulses is carried out. By this means, segmented nanowires can be produced.

Nanowires and method for the production thereof

The invention concerns a nanowire structural element suited for use in a microreactor system or microcatalyzer system.

Nanowires and method for the production there of

The invention concerns a nanowire structural element which is suited for implementation in, for example, a microreactor system or microcatalyzer system. For the production of the nanowire structural element, a template based process is used wherein the electrochemical deposition of the nanowires in nanopores is ideally carried out at least until caps are formed and said caps ideally are at least partially merged together. After reinforcing the two cover layers the structured hollow chamber between the two cover layers is cleared by dissolving the template foil and removing the dissolved template material, wherein the two cover layers remain intact. In this manner, a stable sandwich-like nanostructure is constructed with a two-dimensional hollow chamber-like structure in the plane parallel to the cover layers contained on both sides by the cover layers and permeated in a column-like manner with nanowires.
