TEM, FTIR, spectrophotometry characterized the morphology, structure and dispersion stability of nanoparticles respectively. The results show that the inorganic nanoparticles in the aqueous solution can redisperse more effectively through ultrasonic irradiation than by conventional stirring, which was the basis for monomers to polymerize on the surface of nanoparticles. By selecting proper nanoparticles and monomers, the long-stable latexes were successfully prepared.
