Surface-modified zirconia nanocrystal particle and method for producing same

Abstract

The invention provides a surface-modified zirconia nanocrystal particle, wherein the surface of the zirconia nanoparticle is modified by organic sulfonyloxy groups, and a method of producing a zirconia nanocrystal particle whose surface is modified by carbonyloxy groups, organic phosphoryloxy groups or aryloxy groups. This makes it possible a highly stable surface-modified zirconia nanocrystal particle having a solvent dispersibility by a simple method. Further, it is possible to the surface-modified zirconia nanocrystal particle of the invention is equipped with a surface modifier having a structure that can be easily substituted with a desired functional group according to use. Furthermore, it is possible to the method of producing the surface-modified zirconia nanocrystal particle which is capable of easily producing that.
