REVERSED MICELLAR SOLUTION, INORGANIC NANOPARTICLE, AND METHOD FOR PREPARING NANOPARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a reversed micellar solution having long-term stability and a monodisperse inorganic nanoparticle which is prepared by using the reversed micellar solution having long-term stability and has the particle size to be hardly varied and the composition to be hardly varied among the particles, and to provide a method for preparing the inorganic nanoparticle.;SOLUTION: The reversed micellar solution comprises water, a hydrophobic organic solvent, a surfactant, and a hydrophilic organic solvent having 0-5 solubility parameter difference on the basis of the solubility parameter of the hydrophobic organic solvent or comprises water, the hydrophobic organic solvent, the surfactant, and the hydrophilic organic solvent having ±1.5 difference of (an inorganic value)/(an organic value) on the basis of (the inorganic value)/(the organic value) of the surfactant. The hydrophilic organic solvent content is 2-300 millimoles per 1 liter-total volume of the reversed micellar solution. The inorganic nanoparticle can be obtained by the preparing method using the reversed micellar solution.;COPYRIGHT: (C)2009,JPO&INPIT
