Due to the miniaturization of electronic devices, attention has been paid to a material fixing method using printed electronics (PE). As a material that can be adapted to this, copper nanoparticles are important materials because of their low resistance, low cost, and electromigration resistance, but copper nanoparticles are easily oxidized and have a property of causing an increase in resistance. In this study, we investigated the possibility of suppressing oxidation during heat sintering by synthesizing copper sub-microparticles with oxidation resistance and examining the dispersion medium when preparing paste.
