Definitions
- the invention relates to a method for producing a coating comprising carbon nanotubes, fullerenes and / or graphenes on a substrate, comprising applying carbon nanotubes, fullerenes and / or graphenes to a tin-containing coating and introducing the carbon nanotubes, fullerenes and / or or graphene in the coating by mechanical or thermal treatment.
- the invention further relates to the coated substrate produced by the method according to the invention and to the use of the coated substrate as an electromechanical component.
- Carbon nanotubes were discovered by Sumio lijama in 1991 (see S. lijama, Nature, 1991, 354, 56). lijama found in the soot of a fullerene generator under certain reaction conditions tubular structures of only a few 10 nm diameter, but up to several micrometers in length. The compounds he found consisted of several concentric graphite tubes, which got the name multi-walled carbon nanotubes (MWCNTs). Shortly thereafter, lijama and Ichihashi became single-walled CNTs of about 1 nm diameter, which were correspondingly called single-wall carbon nanotubes (SWCNTs) (see S. lijama, T. Ichihashi, Nature, 1993, 363, 6430).
- MWCNTs multi-walled carbon nanotubes
- CNTs are e.g. their mechanical tensile strength and stiffness of about 40 GPa and 1 TPa, respectively (20 and 5 times higher than steel).
- the carbon nanotubes belong to the family of fullerenes and have a diameter of 1 nm to several 100 nm.
- Carbon nanotubes are microscopic tubular structures (molecular nanotubes) made of carbon. Their walls, like the fullerenes or, like the planes of the graphite, consist only of carbon, the carbon atoms occupying a honeycomb-like structure with six corners and three binding partners each (dictated by SP 2 hybridization).
- the diameter of the tubes is usually in the range of 1 to 50 nm, but also tubes were made with only 0.4 nm diameter. Lengths of several millimeters for single tubes and up to 20 cm for tube bundles have already been achieved.
- the synthesis of the carbon nanotubes usually takes place by deposition of carbon from the gas phase or a plasma.
- the current carrying capacity is estimated to be 1000 times higher than copper wires, the thermal conductivity is at room temperature with 6000 W / m * K almost twice as high as that of Diamant, the best natural occurring thermal conductor.
- the carbon nanotubes belong to the group of fullerenes.
- Fullerenes are spherical molecules of high symmetry carbon atoms, which represent the third elemental modification of carbon (besides diamond and graphite).
- the preparation of the fullerenes usually takes place by evaporating graphite under reduced pressure and under a protective gas atmosphere (eg argon) with resistance heating or in the arc.
- a protective gas atmosphere eg argon
- Graphenes are monatomic layers of sp 2 -hybridized carbon atoms. Graphenes show very good electrical and thermal conductivity along their plane. Graphs are represented by splitting graphite into its basal planes. Initially, oxygen is intercalated. The oxygen reacts partially with the carbon and leads to a mutual repulsion of the layers. Subsequently, the graphenes are suspended and, depending on the intended use, embedded in polymers, for example.
- Another way of displaying individual graphene layers is to heat hexagonal silicon carbide surfaces to temperatures in excess of 1400 ° C. Because of the higher vapor pressure of silicon, the silicon atoms evaporate faster than the carbon atoms. Thin layers of monocrystalline graphite, consisting of a few graphene monolayers, then form on the surface.
- Tin or tin alloys are commonly used to solder electrical contacts, for example to bond together copper wires.
- tin or tin alloys are often applied to connectors to improve the coefficient of friction, protect against corrosion and also contribute to improving the conductivity.
- the problem with tin or tin alloys is in particular the softness of the metal or of the alloy, so that in particular in the case of frequent dissolution and Connecting connectors and vibrations the tin-containing coating is worn and thus lost the benefits of the tin-containing coating.
- the object of the present invention was thus to provide a coating of a tin-containing material which ensures a lower tendency to wear and / or an improved friction corrosion behavior with constant or improved properties relating to the coefficient of friction, conductivity and the like.
- the object is achieved by a method for producing a carbon nanotube, fullerene and / or graphene-containing coating, comprising the application of carbon nanotubes, fullerenes and / or graphene on a tin-containing coating and introducing the carbon nanotubes, fullerenes and / or Graphene in the coating by mechanical or thermal treatment.
- the substrate on which the tin-containing coating is located is preferably a metal, more preferably copper and its alloys. Between the tin-containing coating and the substrate, at least one further intermediate layer can advantageously also be applied.
- tin-containing coating on the substrate tin or a tin alloy is preferably used.
- the carbon nanotubes, fullerenes and / or graphene are applied or introduced, wherein the coating metal in the application or incorporation of the carbon nanotubes, fullerenes and / or graphene solid, liquid or doughy may be present.
- the carbon nanotubes, fullerenes and / or graphenes are introduced into the tin-containing coating, which can be done by mechanical or thermal treatment.
- the mechanical treatment comprises exerting mechanical pressure on the carbon nanotubes, fullerenes and / or graphenes. This is preferably done by applying to the carbon nanotubes, fullerenes and / or graphene by means of a roller, a punch, mechanical brushes, by spraying or by blowing the mechanical pressure.
- the spraying and blowing should be understood as exerting mechanical pressure.
- the tin-containing coating can be solid in the application of the carbon nanotubes, fullerenes and / or graphenes (ie in solid state) and the introduction of the carbon nanotubes, fullerenes and / or graphene in the coating by applying mechanical pressure to the carbon -Nanorschreiben, fullerenes and / or graphene by means of a roller, a stamp or mechanical brushing done.
- the coating may be liquid or doughy, with the introduction of the carbon nanotubes, fullerenes and / or graphenes into the coating / the coating metal by applying mechanical pressure to the carbon nanotubes. Nanotubes, fullerenes and / or graphene by means of a roller, a stamp, mechanical brushes, by spraying or by blowing. If the coating is liquid, the melting temperature of the coating can be undershot when introducing the carbon nanotubes, fullerenes and / or graphenes so that the carbon nanotubes, fullerenes and / or graphenes are fixed in the layer.
- the introduction of the carbon nanotubes, fullerenes and / or graphenes into the coating can also be effected thermally.
- the thermal treatment comprises heating the coating to a temperature below or above the melting point of the coating. Heating to a temperature below the melting point of the coating leads here to a doughy state and heating to a temperature above the melting point of the coating thus leads to a liquid state of the coating.
- the coating is solid upon application of the carbon nanotubes, fullerenes and / or graphenes and is then heated to a temperature above the melting point of the coating.
- the carbon nanotubes, fullerenes and / or graphene melt into the coating material and can be fixed by cooling the coating material below the melting point.
- the coating is liquid in the application of the carbon nanotubes, fullerenes and / or graphene and is then brought to a temperature below the melting point of the coating, whereby the penetrated into the liquid coating carbon nanotubes, fullerenes and / or graphene are fixed.
- the coating is solid in the application of the carbon nanotubes, fullerenes and / or graphenes and is then heated to a temperature below the melting point of the coating. This process is equivalent to tempering, whereby the carbon nanotubes, fullerenes and / or graphene slowly migrate into the coating material as a result of the doughy state of the coating achieved as a result.
- the application of the carbon nanotubes, fullerenes and / or graphenes to the coating and / or the introduction of the carbon nanotubes, fullerenes and / or graphene into the coating takes place under a normal atmosphere or under protective gas.
- a normal atmosphere in the context of this invention, the normal ambient air is understood.
- Any gas known in the art that provides an oxygen-free atmosphere can be used as the shielding gas.
- nitrogen or argon can be used.
- single-walled or multi-walled carbon nanotubes can be used as powder or dispersed in a suspension as carbon nanotubes.
- the carbon nanotubes, fullerenes and / or graphenes can be provided with a metal coating before being applied to the coating.
- the application of the jacket can be carried out by means of mechanical kneading with a metal.
- a ball mill or an extruder can be used for the mechanical kneading.
- the application of the cladding to the carbon nanotubes, fullerenes and / or graphenes can also be done chemically, for example by applying a metal salt solution, which is subsequently reduced or by applying a metal oxide, which is subsequently reduced.
- Another preferred embodiment is to ultrasonically disperse the carbon nanotubes, fullerenes and / or graphenes in an Sn (alloy) melt to the metal strip and apply them in a shaft with subsequent mechanical stripping.
- the carbon nanotubes, fullerenes and / or graphenes form a composite with one another, ie they are interconnected.
- a graphene on a carbon nanotube is particularly preferably arranged orthogonally at its axial end.
- the invention also provides a coated substrate which has been produced by the process according to the invention.
- the substrate is preferably copper or a copper-containing alloy or comprises copper or a copper-containing alloy or Al or an Al alloy or Fe or a Fe alloy. Alloy. It may also be advantageous that intermediate layers are applied between the tin-containing coating and the substrate.
- coated substrate according to the invention is very well suited as an electromechanical component or stamped grid, for example as a switching element, plug connection and the like.
