Abstract
Monodispersed metal nanoparticles are prepared by preparing a homogeneous metal complex solution by mixing metal salt with a complexing agent in solvent. A precipitating agent is added into the homogeneous metal complex solution to form a slurry. A homogeneous mixture of reducing agent and solvent is added to perform reducing reaction on the slurry to form metal nanoparticles in a controlled environment under gas purge. A capping agent is added to modify surface properties of metal nanoparticles. The metal nanoparticles are washed and the metal nanoparticles are recovered by phase extraction or centrifugation. The technique can be used to prepare conductive pastes with bimodal particle size distribution.
