Atmospheric pressure plasmas offer the possibility of activating and modifying surfaces of a wide variety of materials by the input of energy or functionalizing them by the deposition of coatings.

By using atmospheric pressure plasmas, for example, wet chemical processes and various vacuum plasma processes can be replaced.

The processing of materials that are not suitable for vacuum and workpieces with large dimensions or web material is just as possible as the homogeneous treatment of large surfaces or the targeted application to individual edges or structures.

Examples for the functionalization of surfaces with atmospheric pressure plasma are

  • Transmission,
  • Liability,
  • Barrier effect,
  • Self-cleaning,
  • Scratch resistance,
  • Marker function,
  • Electrochromy,
  • Superfine cleaning
  • Bactericity and
  • electrical conductivity.

New applications include barrier coatings on plastics, marker coatings (plagiarism protection), antimicrobial effect of plasmas and antibacterial coatings.
