Methods for surface modification of non-dispersible metal nanoparticles and modified metal nanoparticles for inkjet by the same method

摘要

A method for surface modification of non-dispersible metal nanoparticles comprises mixing metal nanoparticles having an amorphous carbon layer on the surface with an alcohol or thiol solvent, mixing a capping molecule having a carboxylic head group in the mixed solution, and separating the metal nanoparticles from the mixed solution and the metal nanoparticles for inkjet printing thus modified.
