SYNTHESIS OF COPPER NANOPARTICLES MANUFACTURED BY USING CARBIDE-BASED ELECTRIDE AND ORGANIC COPPER COMPOUNDS AND MANUFACTURING OF CONDUCTIVE INK BY USING COPPER NANOPARTICLES

摘要

The present invention provides copper nanoparticles, wherein oxidation of copper is restricted, and an average particle diameter is around 10 nm to fall a melting point and provide high dispersibility. Moreover, a simple ultrasonic treatment process can remove an electride for the copper nanoparticles to be appropriately used for a conductive copper nano ink material. The present invention provides use of an electride performing a role of a protector to prevent oxidation. According to the present invention, the manufactured copper nanoparticles have a small-sized particle, and high dispersibility to be helpfully used as a conductive copper ink material.;COPYRIGHT KIPO 2019
