Magneto-rheopectic Boron-organo-siliconoxide (MrBos)

This project concerns research based on preliminary results from the DFG funded project "Untersuchung der elektrischen Eigenschaften von magnetoaktiven Polymeren" in the DFG-Schwerpunktprogramm "Feldgesteuerte Partikel-Matrix-Wechselwirkungen: Erzeugung, skalenübergreifende Modellierung und Anwendung magnetischer Hybridmaterialien".Magnetorheological fluids are thixotropic (shear thinning) and magnetoactive polymers magnetoeleastic. However, Boron-organo-silicon oxide polymers are rheopectic (shear thickening) and have visco-elastic-plastic characteristics. Their mechanical and electrical properties open up a completely new and hitherto neglected area of research.The effects are time dependent but repeatable. Potential applications include magnetically controlled frequency dependent devices, magnetic sensor systems, weighting elements for neural networks, etc.
