Gemäß einer zweiten Lehre der vorliegenden Erfindung wird die oben aufgezeigte Aufgabe durch ein Verfahren zur Herstellung eines Bandes oder einer Folie dadurch gelöst, dass die thermisch und/oder elektrisch hochleitfähigen According to a second teaching of the present invention, the above-described object is achieved by a method for producing a tape or a film in that the thermally and / or electrically highly conductive

Funktionspartikel durch Ausübung einer mechanischen Kraft in die Oberfläche des erfindungsgemäßen Bandes oder der Functional particles by exerting a mechanical force in the surface of the tape according to the invention or the
erfindungsgemäßen Folie eingedrückt werden. Dies hat den Vorteil, dass die Aluminiumoxidschicht auf der Oberfläche des erfindungsgemäßen Bandes oder der erfindungsgemäßen Folien auf einfache Weise durchdrungen werden kann, so dass Kontakt mit dem darunterliegenden Kern des erfindungsgemäßen Bandes oder der erfindungsgemäßen Folie besteht. Darüber hinaus ist das mechanische Einbringen von Partikeln auf die Oberfläche eines Werkstücks besonders einfach und umweltfreundlich. Gemäß einer ersten Ausgestaltung des Verfahrens zur Pressed film according to the invention. This has the advantage that the aluminum oxide layer on the surface of the tape according to the invention or the films according to the invention can be penetrated in a simple manner, so that there is contact with the underlying core of the tape according to the invention or the film according to the invention. In addition, the mechanical introduction of particles onto the surface of a workpiece is particularly simple and environmentally friendly. According to a first embodiment of the method for
Herstellung eines erfindungsgemäßen Bandes oder einer erfindungsgemäßen Folie wird vor dem mechanischen Einbringen der Funktionspartikel in die Oberfläche des Bandes oder der Folie ein Haftvermittler oder ein Primer auf das Band oder die Folie aufgetragen. Der Primer oder der Haftvermittler gewährleisten, dass die nanoskalierten Funktionspartikel auf dem Aluminiumband oder der Folie auf einfache Weise Production of a tape according to the invention or of a film according to the invention is effected before the mechanical introduction the functional particles in the surface of the tape or the film an adhesion promoter or a primer applied to the tape or the film. The primer or primer ensures that the nano-scaled functional particles on the aluminum tape or film are simple
angeordnet werden können, ohne dass diese aufgrund ihrer Größe beispielsweise durch thermische Energie oder durch einen Luftzug vom Band oder der Folie entfernt werden können. Darüber hinaus besteht die Möglichkeit über den can be arranged without these can be removed because of their size, for example by thermal energy or by a draft from the tape or the film. In addition, there is the possibility of the
Haftvermittler oder den Primer die Oberfläche des Primer or the surface of the primer

Auf besonders einfache Art und Weise gelingt das mechanische Einbringen der Funktionspartikel in die Oberfläche des Bandes oder der Folie dadurch, dass die Funktionspartikel in die Oberfläche des Bandes oder der Folie eingewalzt werden. In a particularly simple manner, the mechanical introduction of the functional particles into the surface of the strip or film is achieved by rolling the functional particles into the surface of the strip or film.
Einerseits können hierdurch übliche Verfahrensschritte zur Herstellung von Bändern oder Folien aus Aluminium oder einer Aluminiumlegierung genutzt werden, so dass nur geringe On the one hand, this makes it possible to use customary process steps for the production of strips or foils made of aluminum or an aluminum alloy, so that only a small amount can be used
Investitionskosten notwendig sind, um die erfindungsgemäßen Bänder oder Folien herzustellen. Andererseits kann jeder beliebige Walzschritt in der Herstellung des  Investment costs are necessary to produce the tapes or films of the invention. On the other hand, any rolling step in the manufacture of the
erfindungsgemäßen Bandes oder der erfindungsgemäßen Folie genutzt werden um die Funktionspartikel auf der Oberfläche des Bandes derart anzuordnen, dass diese die Oxidschicht des Bandes oder der Folie zumindest teilweise durchdringen. Tape of the invention or the film according to the invention are used to the functional particles on the surface of the tape to be arranged such that they penetrate the oxide layer of the tape or the film at least partially.
Prinzipiell sind dabei alle Zwischenwalzschritte dazu In principle, all intermediate rolling steps are involved
geeignet, entsprechend die Funktionspartikel in die suitable, according to the functional particles in the
Oberfläche einzubringen. Vorzugsweise erfolgt das Einwalzen der Funktionspartikel durch Warmwalzen, Kaltwalzen und/oder durch Dressierwalzen. Beim Dressierwalzen wird in der Regel nur eine geringe oder keine Dickenänderung des Bandes oder der Folie erzielt, sondern eine spezifische Oberflächentextur in das Band oder die Folie eingebracht. Dieser Vorgang kann ebenso genutzt werden zur Einbringung der Funktionspartikel wie das Surface to bring. The rolling-in of the functional particles is preferably carried out by hot rolling, cold rolling and / or temper rolling. In temper rolling, only a small or no change in thickness of the tape or the film is achieved in the rule, but a specific surface texture is introduced into the tape or the film. This process can also be used to introduce the functional particles as the
üblicherweise durchgeführte Kaltwalzen oder Warmwalzen des Bandes oder der Folie in der Fertigung. Dabei gelingt das Einwalzen der Funktionspartikel unabhängig davon, ob das Band aus einem Walzbarren hergestellt oder direkt gegossen und gewalzt worden ist. usually performed cold rolling or hot rolling of the strip or film in the production. In this case, the rolling of the functional particles succeeds regardless of whether the band has been produced from a rolling bar or cast directly and rolled.
Vorzugsweise wird gemäß einer weiteren Ausgestaltung des Verfahrens vor dem Einwalzen der Funktionspartikel eine Preferably, according to a further embodiment of the method before the rolling of the functional particles is a
Oberflächenstruktur in das Band oder die Folie eingebracht und die Funktionspartikel auf der texturierten Oberfläche verteilt und anschließend eingewalzt. Die texturierte  Surface structure is introduced into the tape or the film and distributed the functional particles on the textured surface and then rolled. The textured
Oberfläche kann beispielsweise dazu benutzt werden, um spezifische Verteilungen der Funktionspartikel zu erzielen oder die Haftung der Partikel an der Oberfläche des Bandes oder der Folie zu verbessern, beispielsweise indem sich die nanoskalierten Partikel in Vertiefungen der Textur sammeln. Eine besonders schonende Einbringung der Funktionspartikel in das erfindungsgemäße Band oder die erfindungsgemäße Folie wird dadurch erreicht, dass die Funktionspartikel in 1 bis 10 Walzschritten eingewalzt werden. Bei sehr großen Surface may be used, for example, to achieve specific distributions of the functional particles or to improve the adhesion of the particles to the surface of the belt or film, for example by collecting the nanoscale particles in pits of the texture. A particularly gentle introduction of the functional particles into the tape or film according to the invention is achieved by rolling the functional particles in 1 to 10 rolling steps. For very large
Dickenabnahmen kann problematisch sein, dass die Thickness decreases can be problematic that the
Funktionspartikel nicht nur in der Oberflächenschicht vorhanden sind. Durch die Verwendung von mehreren Functional particles are not only present in the surface layer. By using several
Walzschritten zum Einbringen der Funktionspartikel können die Dickenabnahmen pro Walzschritt verringert werden, so dass die Funktionspartikel nur in die Oberflächenbereiche Walzschritten for introducing the functional particles, the Thickness decreases per rolling step are reduced so that the functional particles only in the surface areas
eingearbeitet werden. Mit zunehmender Anzahl der Walzschritte wird selbstverständlich der Aufwand zur Herstellung des erfindungsgemäßen Bandes oder der Folie größer. be incorporated. As the number of rolling steps increases, it goes without saying that the outlay for producing the strip or film according to the invention becomes greater.
Gemäß einer nächsten Ausgestaltung des erfindungsgemäßen Verfahrens werden bevorzugt die Funktionspartikel vor dem mechanischen Einbringen in die Oberfläche in Dispersions-, Suspensions- oder Pulverform auf der Oberfläche des Bandes oder der Folie aufgebracht. Werden die Funktionspartikel in Dispersions- oder Suspensionsformen aufgebracht, kann auf einfache Weise ein unabsichtliches Entfernen der According to a next embodiment of the method according to the invention, the functional particles are preferably applied to the surface of the tape or the film prior to mechanical introduction into the surface in dispersion, suspension or powder form. If the functional particles are applied in dispersion or suspension forms, inadvertently removing the
Funktionspartikel von der Oberfläche des Bandes vor dem Walzen verhindert werden, da diese mit der flüssigen Functional particles are prevented from the surface of the strip before rolling, as these are mixed with the liquid
Dispersion oder Suspension auf dem Band oder der Folie vorliegen. Darüber hinaus gelingt die Verteilung der  Dispersion or suspension on the belt or the film. In addition, the distribution of the succeeds
Funktionspartikel auf der Oberfläche des Bandes oder der Folie besonders einheitlich. Werden die Funktionspartikel in Pulverform auf das Band oder die Folie aufgebracht, kann beispielsweise das auf dem Band oder der Folie vorhandene Walzöl zum Anhaften der Funktionspartikel auf der Oberfläche des Bandes oder Folie genutzt werden. Walzöl ist ein während der mechanischen Verarbeitung der Bänder oder Folien ständig vorhandenes Medium, dessen Verhalten vor und nach dem Walzen sehr gut bekannt ist. Darüber hinaus werden keine Functional particles on the surface of the tape or film particularly uniform. If the functional particles are applied in powder form to the tape or the film, for example, the rolling oil present on the tape or the film can be used to adhere the functional particles to the surface of the tape or film. Rolling oil is a constantly present during the mechanical processing of the tapes or films whose behavior is very well known before and after rolling. In addition, no
zusätzlichen Stoffe zum Aufbringen der Funktionspartikel auf das Band oder die Folie benötigt. Schließlich wird die oben aufgezeigte Aufgabe durch eine Verwendung eines erfindungsgemäßen Bandes oder einer additional substances needed to apply the functional particles on the tape or the film. Finally, the above object is achieved by using a belt according to the invention or a

Fig. 1 zeigt zunächst in einer schematischen Schnittansicht ein Ausführungsbeispiel des Bandes 1, welches auf beidenFig. 1 shows first in a schematic sectional view of an embodiment of the band 1, which on both
Seiten eine Oxidschicht 2 aufweist. In die obere Oxidschicht 2 sind thermisch und/oder elektrisch hochleitfähige Side has an oxide layer 2. In the upper oxide layer 2 are thermally and / or electrically highly conductive
Funktionspartikel 3 eingearbeitet, welche die Oxidschicht 2 teilweise durchdringen. Das in Fig. 1 dargestellte Functional particles 3 incorporated, which partially penetrate the oxide layer 2. The illustrated in Fig. 1
Ausführungsbeispiel eines Bandes 1 weist einseitig Embodiment of a band 1 has one-sided
eingebrachte Funktionspartikel auf. Selbstverständlich ist denkbar, in beiden Oxidschichten des Bandes 1 hochleitfähige Funktionspartikel 3 vorzusehen. Die hochleitfähigen introduced functional particles on. Of course, it is conceivable to provide highly conductive functional particles 3 in both oxide layers of the strip 1. The highly conductive
Funktionspartikel 3 stehen im Kontakt mit dem Kernmaterial la des Bandes 1, so dass beispielsweise bei einer Stromführung die Funktionspartikel 3 den elektrischen Strom ohne Probleme in den Kernbereich des Bandes la, welcher eine sehr gute Leitfähigkeit besitzt, weiterleiten. Die Aluminiumoxidschicht 2 spielt dann für die elektrische und/oder thermische Functional particles 3 are in contact with the core material 1a of the strip 1, so that, for example, in the case of a current lead, the functional particles 3 pass on the electric current without problems into the core region of the strip 1a, which has a very good conductivity. The aluminum oxide layer 2 then plays for the electrical and / or thermal
Leitfähigkeit des erfindungsgemäßen Bandes 1 oder der erfindungsgemäßen Folie keine Rolle mehr. Das Conductivity of the tape 1 of the invention or the film of the invention no longer matter. The
erfindungsgemäße Band 1 kann beispielsweise eine Dicke von 15mm bis 0,1mm aufweisen. Erfindungsgemäße Folien haben dagegen Dicken von ΙΟΟμπι bis 10pm. Tape 1 according to the invention may, for example, have a thickness of 15 mm to 0.1 mm. On the other hand, films according to the invention have thicknesses of ΙΟΟμπι to 10pm.
Wie in der den Ausschnitt A vergrößernden Fig.2 zu erkennen ist, sind als thermisch und/oder elektrisch hochleitfähige Funktionspartikel nanoskalierte Karbonröhrchen, sogenannte "carbon nanotubes" (CNT) verwendet worden. Es hat sich gezeigt, dass insbesondere nanoskalierte Karbonröhrchen oder Karbonfasern ohne weiteres durch Walzen in das Band oder die Folie eingebracht werden können, so dass diese die immer vorhandene Oxidschicht 1 zumindest teilweise durchdringen und darüber hinaus eine feste Verbindung mit dem Kern la des Bandes oder der Folie aufweisen. Mit dem erfindungsgemäßen Band oder der erfindungsgemäßen Folie stehen damit im As can be seen in FIG. 2, which enlarges the detail A, nano-scaled carbon tubes, so-called "carbon nanotubes" (CNT), have been used as thermally and / or electrically highly conductive functional particles. It has been found that in particular nanoscale carbon tubes or carbon fibers can be easily introduced by rolling in the tape or the film, so that they always existing oxide layer 1 penetrate at least partially and also have a firm connection with the core la of the tape or the film. With the tape according to the invention or the film according to the invention thus stand in the
Hinblick auf deren elektrische und/oder thermische Regard to their electrical and / or thermal
Leitfähigkeit deutlich verbesserte Bänder oder Folien zur Verfügung .  Conductivity significantly improved tapes or films available.
Wie bereits zuvor erläutert können die thermisch und/oder elektrisch hochleitfähigen Funktionspartikel auch während des Dressierwalzens in das Band oder die Folie eingearbeitet werden. Als Resultat ergibt sich ein wie in Fig. 3 As already explained above, the thermally and / or electrically highly conductive functional particles can also be incorporated into the strip or foil during temper rolling. As a result, a result as in FIG. 3
schematisch dargestelltes Band mit einer Oberflächentextur, in welcher die thermisch und/oder elektrisch hochleitfähigen Funktionspartikel angeordnet sind. Die Oberflächenstruktur 4 ist damit thermisch und/oder elektrisch hochleitfähig . schematically illustrated band with a surface texture in which the thermally and / or electrically highly conductive functional particles are arranged. The surface structure 4 is thus highly thermally and / or electrically conductive.

reduzieren. Über eine Vorrichtung 6 werden beispielsweise in Suspensions- oder Dispersionsform thermisch und/oder to reduce. About a device 6, for example, in suspension or dispersion form thermally and / or
elektrisch hochleitfähige Funktionspartikel 3 auf das Band gebracht bzw. auf der Oberfläche des Bandes verteilt. Das aufbringender Funktionspartikel 3 kann aber auch in electrically highly conductive functional particles 3 placed on the belt or distributed on the surface of the belt. The applying functional particles 3 can also in
Pulverform geschehen. Sind die Funktionspartikel auf dem Band verteilt, werden diese über die Arbeitswalzen 5 in die Powder form happen. Are the functional particles distributed on the tape, they are on the work rolls 5 in the
Oberflächenschicht derart eingearbeitet, dass diese die Oxidschicht zumindest teilweise durchdringen. In Fig. 4 ist der Einfachheit halber die Oxidschicht nicht dargestellt. Die Arbeitswalzen 5 können beispielsweise Arbeitswalzen eines Warmwalz-, eines Kaltwalz- oder eines Dressierwalzgerüsts sein . Surface layer incorporated so that they at least partially penetrate the oxide layer. In Fig. 4, the oxide layer is not shown for the sake of simplicity. The work rolls 5, for example, work rolls of a Hot rolling, a cold rolling or a temper rolling mill.
