“…Polymers are the most effective of the above stabilizers, since the polymeric layer is dense enough to effectively slow down the oxygen penetration to the NP surface and, accordingly, the oxidation rate. The most widely used, both in organic solvents and in aqueous medium, is PVP which forms a densely packed, adsorbed layer on the surface of the copper NPs . Long‐term stability of copper NPs to oxidation was achieved by performing synthesis in water in the presence of CTAB and CTAB‐PVP mixture .…”

This is a review on recent developments in the field of conductive nanomaterials and their application in printed electronics, with particular emphasis on inkjet printing of ink formulations based on metal nanoparticles, carbon nanotubes, and graphene sheets. The review describes the basic properties of conductive nanomaterials suitable for printed electronics (metal nanoparticles, carbon nanotubes, and graphene), their stabilization in dispersions, formulations of conductive inks, and obtaining conductive patterns by using various sintering methods. Applications of conductive nanomaterials for electronic devices (transparent electrodes, metallization of solar cells, RFID antennas, TFTs, and light emitting devices) are also briefly reviewed.

“…Cu nanoparticles are usually protected with a capping agent in order to minimize oxidation and control the growth of a crystal by decreasing the surface energies of crystals [10]. However, the capping agents or stabilizers can significantly reduce the oxidation but may not prevent it completely because of their molecular motion [5,15].…”

Development of improved methods for the synthesis of copper nanoparticles is of high priority for the advancement of material science and technology. Herein, starch-protected zero-valent copper (Cu) nanoparticles have been successfully synthesized by a novel facile route. The method is based on the chemical reduction in aqueous copper salt using ascorbic acid as reducing agent at low temperature (80°C). X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray spectroscopy measurements were taken to investigate the size, structure and composition of synthesized Cu nanocrystals, respectively. Average crystallite size of Cu nanocrystals calculated from the major diffraction peaks using the Scherrer formula is about 28.73 nm. It is expected that the outcomes of the study take us a step closer toward designing rational strategies for the synthesis of nascent Cu nanoparticles without inert gas protection.

“…11. Absorption bands for copper oxide nanoparticles are reported to be within the range of 500-600 nm [28,29], because of surface plasmon resonance, which is strongly dependent on particle size and morphology. A broad absorption peak for the copper oxide nanoparticles was observed at 493 nm, which should blue-shift as particle size decreases due to quantum size effects [30].…”
