Abstract

The synthesis, characterization and evidence of magnetostrictive properties of blends between one ionic polyurethane with carboxylic units and magnetostrictive micropowders (Fe78Si9B13), as well as nanopowders (Fe68,5Co10Sm1,5B20) is reported. The incorporation of magnetic particles in the polyurethane matrix lead to a magnetic behavior directly dependent on their density and dimensions. The best response was achieved for the micropowders with the diameter within 100 – 150 μm range. A good behavior was also evidenced for the compact system composed of microparticles with the diameter less than 60 μm.
