Abstract
Functional nanoparticle-dispersed composite polymer materials were prepared. Metal oxide nanoparticles such as BaTiO3 (primary diameter: 20nm) and three sizes of TiO2 (primary diameter: 7, 15, 20nm) were dispersed into acrylic monomer by means of beads mill filled with fine beads (50μm in diameter), and the nanoparticle-dispersed monomers were polymerized to obtain nanocomposite polymers by the suspension polymerization. The morphology, the nanoparticle dispersibility and the compressive strength of prepared polymer were evaluated. As a result, the TiO2-dispersed acrylic polymer spheres were fairly uniform in size with the diameter of several micrometers, and had relatively high compressive strength of 257MPa. It was also confirmed from the transmission electron microscope that the nanoparticles were well-dispersed in the polymer matrix.
