Titanium oxide (titania) particles are induced from Ti⁴⁺ to Ti³⁺ by UV irradiation, and transition from diamagnetism to paramagnetism. However, Ti³⁺ is easily oxidized in the atmosphere and returns to Ti⁴⁺. In this study, the titania particles were synthesized in a polymer matrix, and the titania particles were successfully produced and highly dispersed. In addition, the polymer matrix can control oxygen permeability, leading to the stabilization of Ti³⁺. We will describe the stabilization of unstable fine particles from the viewpoint of composite materials.
