Plastic magnet

Plastic magnets are non-metallic plastics with permanent magnetic properties. One example is the material PANiCNQ , which is a combination of polyaniline (PAni) and tetracyanoquinodimethane (TCNQ) and was developed in 2004 by Naveed A. Zaidi et al. at the University of Durham . PANiCNQ is the first known non-metallic plastic that shows ferrimagnetic properties at room temperature .

The polyaniline used as the starting material is electrically conductive and is processed in a combination of tetracyanoquinodimethane in a chain polymerization , which takes around 3 months to complete. The resulting substance then shows permanent magnetic (hard magnetic) properties. The Curie temperature of the material is 350 K (76.85 ° C ).

Plastic magnets are not to be confused with commercially available flexible magnets, which are made from metallic magnetic particles and are pressed into a non-magnetic plastic carrier material for the purpose of shaping.
