Polymer composites with magnetostrictive properties
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
