Various metallic copper nanoparticles ( CuNPs ) were successfully synthesized through solution‐phase transport chemical reaction with controlled parameter molar ratio: polyvinylpyrrolidone surfactants, sodium hypophosphite reducing agents, and copper sulfate precursors. Scanning electron and transmission electron micrographs revealed the sizes, distributions, and aggregation of the CuNPs obtained with varying molar ratio of synthesis parameters in an ethylene glycol solvent. Moreover, X‐ray diffraction analysis confirmed the presence of face‐centered cubic microstructures and reduction products of copper ion. The nucleation and growth of CuNPs varied with the extent of chemical reaction. The origins of the differently produced sizes and distributions of the CuNPs were considered.
