  • Molecule-based magnetic polymers and methods
    Patent number: 8658751
    Abstract: Molecule-based magnetic polymers with reasonably high Curie temperature and methods of preparing are provided. In particular, magnetic polymers having repeating units of an organometallic monomer covalently bonded to a monomer having a plurality of unpaired electrons are disclosed. Intrinsically homogeneous magnetic fluids (liquid magnets) and methods of preparing are also provided.
    Type: Grant
    Filed: October 12, 2011
    Date of Patent: February 25, 2014
    Assignee: The University of Akron
    Inventors: Chang Dae Han, Wenyi Huang

  • MOLECULE-BASED MAGNETIC POLYMERS AND METHODS
    Publication number: 20100155649
    Abstract: Molecule-based magnetic polymers with high Curie temperature and methods of preparing are provided. In particular, magnetic polymers having repeating units of an electron-donor metallocene-containing monomer covalently bonded to an electron-acceptor monomer having a plurality of unpaired electrons are disclosed. Intrinsically homogeneous magnetic fluids (liquid magnets) and methods of preparing are also provided.
