Definitions

  • the invention relates to a method for producing a component with a nanostructured coating, in which the nanostructuring of the coating is produced using nanoparticles. Furthermore, the invention relates to polymer films in which nanoparticles are incorporated.
  • the object of the invention is to provide a process for the production of nanostructured coatings with any layered material. specify a simple coating with a relatively free choice of the layer materials is possible and a uniform distribution of nanoparticles in the coating can be generated.
  • This invention is achieved with the aforementioned method for producing a component with a nanostructured coating by carrying out the following method steps for nanostructuring of the coating using nanoparticles.
  • a film filled with the nanoparticles to be used is made of a polymeric material.
  • the film is applied to the surface to be coated of the component.
  • the polymer forming the film by a post-treatment is removed from the surface, wherein the nano-Parti ⁇ kel form the coating.
  • the layer components do not have to be formed exclusively by the nanoparticles.
  • the nanostructuring consists in this case of the finely dispersed nanoparticle distribution.
  • the nanostructuring can also be generated by the nanoparticles when they form the coating.
  • interactions between the nanoparticles are responsible, which have a strong impact on film formation due to the large surface area in relation to the volume of the nanoparticles.
  • the aftertreatment can also bring about a melting of nanoparticles, which also makes it possible to hold the layer together without the use of further coating materials which could form a matrix for the incorporation of the nanoparticles.
  • the aftertreatment consists in a heat treatment of the component.
  • the destruction of the polymer material is accomplished by a thermal stress that exceeds the thermal capacity of the polymeric material.
  • a heat treatment can advantageously be carried out very easily. It is particularly suitable for large-area components, since the attack occurs during the heat treatment over the entire surface.
  • the aftertreatment can also be carried out with a laser beam or a particle beam, in particular a cold gas coating jet.
  • a laser beam for the aftertreatment used development this only serves to introduce the gen to decompose and remove the polymeric material notwendi ⁇ energy.
  • the coating is formed only from the nanoparticles.
  • the nanoparticles are introduced into the polymer material by adding them directly to the polymer melt in the process of extrusion of the polymer material.
  • One Extrusion process is the most common manufacturing process for semi-finished polymers.
  • the polymer is prepared and a polymer melt extruded from the closing to ⁇ réellema ⁇ TERIAL, wherein the polymer melt is in principle lent suitable for receiving the nanoparticles.

Abstract

La présente invention concerne un procédé servant à produire un composant (20) avec un revêtement (24) contenant des nanoparticules (21). Il est prévu selon l'invention que pour introduire les nanoparticules (21) dans le revêtement (24), une feuille (19) avec les nanoparticules (21) réparties en dispersion est appliquée sur la surface (22) à recouvrir qui est décomposée lors du processus intrinsèque de revêtement par la formation des nanoparticules (21) et n'est donc pas incorporée dans la couche.
