Herausforderung

Foams have a wide range of established applications, for example in building, automotive, air-filtration, upholstering and acoustic and thermal insulation.

Adding a new material property like electric conductivity to foams opens up exciting ­technical possibilities. However, existing metallization methods have so far proven laborious and complex, and often failed to yield homogenous functionalization. The challenge therefore is to develop a simple, efficient method scalable to industrial application.

Innovation

The present innovation, developed at the University of Bayreuth, includes a simple and ­easily scalable chemical process. Using e.g. copper or silver, a homogeneous, metallized foam ­material is produced, thereby combining the advantages of both foams and metals.

Three-dimensional substrates in all shapes and sizes are amenable to the technique. The ­innovative foams show very good electric conductivities of up to 24’000 S/m and an electrical resistivity up to 10 A.

Advantages of the new high-tech foams are:

  • Simple, scalable metallization process using finished foam materials
  • high electric conductivity
  • open-cell structure, breathability & very low weight
  • heat emission at current flow
  • water repellency & antimicrobial properties
  • thermal and acoustic insulation
