IAP - Intrinsic Antimicrobial Polymers

Ref.-Nr. 3158

Keywords: polymers, mould, biocide, hygien, anti-germ

Scientists of the FH Münster developed several novel intrinsic antimicrobial polymers. State of the art antimicrobial polymers are polymers with antimicrobial additives such as silver or copper. Additionally, a further approach is using functionalized monomers, containing amine or quaternary ammonium/phosphonium groups. These monomers can be polymerized to intrinsically microbial polymers. Unfortunately, they suffer from poor material properties (low glass transition temperature, high water uptake). The novel intrinsic antimicrobial polymers overcome these shortcomings. Several groups of polymers have been developed (homopolymers and copolymers) with favorable processing characteristics, e.q. can be used in an injection molding process or press molding. The standard JIS Z 2801 test to quantitatively test the ability to inhibit the growth of microorganisms over a 24 hour period of contact reveals a reduction of up to log 7,1.


  • IAP as thermoplastic or thermoset material (UP-Resin, VE-Resin, VEU-Resin)
  • Cost effective (one patent allows a very cost effective way of production)
  • Cheap and convenient synthesis and processing
  • Variety of possible product applications
  • Environmentally friendly, no biocide additives needed
