Outline of Final Research Achievements

We investigated electrophoretic behaviors of non-ionic polymers containing sulfonyl groups. The negative zeta potential of each polymer dispersion (40 to 20 mV) was also confirmed, when we used various alcohols as the poor solvent, which reveals that the electrophoretic behavior is dependent upon a partial charge separation in the protic solvent (alcohol) at the interface of the dispersion. In this study, we performed electrophoresis of non-ionic nano particles (diameter: ca. 300 nm), prepared via soap-free emulsion copolymerization of vinyl monomers containing a sulfide linkage with styrene　and subsequent oxidation to a sulfonyl group. After electrodeposition (EPD), a structural color was observed, indicating that the monodisperse spheres had attached to the surface and exhibited specific light diffraction.
