  • the invention relates to a method for producing a functional structure on a surface of a functional body, a structural film and a method for producing a structural film.
  • micro- and nanostructures can be used, for example, for biological applications, especially antimicrobial surfaces. These can also be used in the transport sector, for example for flow-optimized riblet surfaces on aircraft or trains. Another application of micro- and nanostructures concerns the optimization of the flow resistance of ships' underwater structures. In the construction sector, micro and nanostructures are used for self-cleaning surfaces. They are also used in the energy sector, for example to increase the efficiency of wind turbines or solar systems. Such structures are often inspired by surfaces from nature. For example, riblet structures have been developed to reduce the flow resistance of bodies with fluid flow around them, based on the rough shark skin.
  • EP 1 135 267 A1 describes a method for the decorative design of a painted substrate surface, in which one or more embossing matrices are pressed into an uncured coating layer, each with a relief on the side to be decorated.
  • One disadvantage of this method is, among other things, that a precise alignment of the embossing dies and a corresponding device have to be arranged on the surface to be decorated.
  • EP 0 428 628 A1 describes structuring a substrate with a pressure belt. This device has the disadvantage that it is particularly not suitable for large substrate surfaces, since the device would have to be moved on the surface.
  • the nano-imprint process in which a film substrate is coated with a radiation-curable or thermally curable lacquer and brought into contact with the structured surface of a tool. The polymerization of the paint is initiated while the tool is in contact with the liquid paint. The surface structures of the tool are thus formed as a negative in the paint.
  • Such films can, for example, be provided with a self-adhesive backing layer and glued to the surface to be coated.
  • EP 2 146 805 A1 describes such a nano-imprint process.
  • the disadvantage of this process is that the film itself forms the surface, so that properties of the film define the properties of the surface.
  • the use of a so-called master film is known to produce a new film with the negative impression of the master film.
  • EP 1 135 267 A1 discloses a method for decoratively designing a painted substrate surface.

  • DE 196 16331 C1 discloses a method for producing a structural film made of thermoplastic.
  • a further disadvantage of many known methods is that the coating has to be hardened using a special hardening process, for example UV radiation. Such methods are often not applicable in industry, for example because the areas are too large, for example the underwater hull of a freighter.
  • the task mentioned at the outset is solved by a method for generating a functional structure on a surface of a Functional body, comprising the steps: providing a structural film with a negative structure which images a corresponding negative of the functional structure, arranging the structural film on a curable coating of the functional body such that the functional structure is generated on the functional body by means of the negative structure, the structural film being arranged in such a way and is designed so that it can be removed for the intended use of the functional body in such a way that the functional structure remains on the surface.
  • the invention is based on the knowledge that films with functional structures are not suitable for a large number of applications because the material of the film generally does not have the required properties like coatings, for example paints. Furthermore, the invention is based on the knowledge that a functional structure can advantageously be produced on the surface of the functional body with a structural film with a negative structure, in particular no additional curing processes for the coating, for example UV irradiation, being required.
  • the structural film can also be used to create large-area functional structures, for example on the underwater ships of freighters, on the wings of watercraft, on the rotor blades of wind turbines and the like.
  • functional structures can be created on a rotor blade of a helicopter or on a wing of an aircraft.
  • the process has the further advantage in aviation and shipping that an already approved or certified material can be used for the coating, whereas the functional structure is created with the structural film that is not used in operation.
  • the process is particularly suitable for applications that place special demands on the coating.
  • the film usually should not be left on the surface as it does not have the appropriate properties. This can be, for example, an anti-fouling property of the coating or, for example be a flow-optimizing property of the functional body.
  • films are often sensitive to mechanical contact, so that, for example, when underwater, contact with the ground, which occurs regularly in practice, leads to damage.
  • the film arranged there can be damaged.
  • the process can be used to produce self-cleaning surfaces if the coating has appropriate properties, these self-cleaning properties being independent of the properties of the structural film.
  • the functional body can be, for example, a hull, in particular an underwater ship, or a propeller of a ship, for example a container ship or a cruise ship. Furthermore, the functional body can be a rotor blade of a wind turbine or a helicopter or a wing of an aircraft. Furthermore, the functional body can be a component of an automobile. It is particularly preferred that the surface of the functional body is a surface that interacts with a fluid, for example air or water, during normal operation.

  • the method further comprises the step: arranging the structural film on a curable coating of the functional body in such a way that the functional structure is produced on the functional body by means of the negative structure. Since the coating can be hardened at this point in time, it can be formed; in particular, the functional structure, for example a relief, can be embossed into it. By arranging the structural film on the coating, the negative structure can be pressed into the coating, so that the functional structure is created on the functional body and in particular on the coating. Creating the functional structure can also be referred to as imprinting.
