| Outline of Final Research Achievements |
Here, we demonstrated the preparation of polymeric magnetic materials based on a three-dimensional (3D) polymer network via holmium atoms, one of the lanthanide elements. By creating the 3D polymer network composed with polyacrylic acid (PAA) and holmium atoms showing trivalent nature, we succeeded in the creation of a new category of the magnetic polymer in which the polymer itself responds to a magnet. In addition, polymeric scaffolds such as polymer-grafted particles made it possible to produce non-colored magnetic composite materials that respond quickly to the magnet. This simple and novel process of using a 3D polymer network via holmium atoms can be used in basic research on magnetic materials and hold a great potential for technological applications, ranging from optical to colored devices.
