NONAQUEOUS ORGANIC-SOLVENT SOLUTION OF METALLIC NANOPARTICLE AND PREPARATION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous organic-solvent solution of metallic nanoparticles, which is stable and has high metal concentration, and to provide a method for efficiently preparing the nonaqueous organic-solvent solution of the metallic nanoparticles.;SOLUTION: The nonaqueous organic-solvent solution of the metallic nanoparticles includes the metallic nanoparticles and a nonaqueous organic solvent, wherein the metal occupies 90 mass% or higher of a solid content in the solution, and the nonaqueous organic solvent is immiscible with water and is an ester-based, ketone-based, alcohol-based or high carboxylic acid-based organic solvent with a specific gravity of 0.9 or more.;COPYRIGHT: (C)2006,JPO&NCIPI
