N2 - Oleylamine stabilized copper nanoparticles with an average diameter of ∼10 nm were obtained by reducing copper chloride with 1-heptanol. Surfactants such as oleylamine, poly (N-vinylpyrrolidone) and oleic acid were used to avoid the agglomeration and growth of the particles during the synthesis and consequent dispersion in organic solvent. The analyses of the samples indicated that oleylamine results to be more suitable to prepare stable copper suspensions in dodecane. The electrical resistivity of the copper thin films prepared by spin coating the copper nanoink and annealed at 250 °C under different atmospheres was less than 35 μΩ-cm, which is closer to the values reported for Cu nanoparticles.
