Abstract
The invention provides a method for manufacturing spherical, monodispersed core-shell type ceria-polymer hybrid nanoparticles including, a mixing step in which a cerium salt and a polymer are mixed together in a high-boiling-point organic solvent to obtain a mixture, and a heating and reflux step in which this mixture is heated and refluxed at a temperature of 110° C. or more to thereby generate a boiling phenomenon in the heating and reflux step, and rapidly cooling the mixture after the heating and reflux step to precipitate cerium oxide, and a liquid dispersion thereof.
