| Outline of Final Research Achievements |
Polymer particles with the diameters ranging from nanometer to micrometers are conventionally prepared by an emulsion of polymer solution and polymerization of monomer, etc. The obtained particles are contacted with the various surfaces and particles themselves via point-contact interactions due to the spherical shape. We herein propose a fabrication procedure of disk-shaped particles deformed by a hot-press technique, and their applications using two-dimensional interactions. The glass transition temperature of the polymers and the pressure at 10 MPa in hot-press process were important parameters to deform spheres to disks. Furthermore, we demonstrated that the unique properties of the disk-shaped particles were induced by their two-dimensional interactions, e.g. high adhesiveness to the surfaces, controlled release of encapsulating materials, and high aggregation between disks.
