Disclosed are: an ionomer nanoparticle dispersion solution formed by dispersing, in a solvent mixture, which comprises water and an alcohol, a perfluorinated ionomer, which has an ion conductive functional group, and carrying out a reaction under a supercritical condition; and a preparation method therefor. The ionomer nanoparticle dispersion solution has a high azeotropic mixture content in a continuous phase, which is a liquid phase, so as to readily remove a solvent therefrom, and thus a product using the ionomer nanoparticle dispersion solution can be readily molded and preparation costs can be reduced. In addition, product uniformity is improved since a perfluorinated ionomer having various ion conductive functional groups and various salts thereof is nano-dispersed, in a narrow molecular weight distribution, in the ionomer nanoparticle dispersion solution. |
