Electrophoretic deposition (EPD) is one of the most important coating methods. This method has various advantages, such as being able to make a coating as a uniform film, even on a complex surface. Recently, we found that non-ionic poly(ester-sulfone) materials show anode selective electrophoretic behavior. In this paper, 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 EPD, a structural color was observed, indicating that the monodisperse spheres had attached to the surface and exhibited specific light diffraction, in which the wavenumber is dependent on the incident angle.
