Understanding the effects of polar and non-polar surfactants on the oxidation performance of copper nanoparticles

Study on the preparation of ascorbic acid reduced ultrafine copper powders in the presence of different protectants and the properties of copper powders based on methionine protection

“…6–9 However, the smaller particle sizes, narrower distribution, higher activity, and easy oxidization pose inevitable limitations on the preparation and storage of the ultrafine copper powder particles. 10 Although various methods exist for preparing ultrafine copper powder particles including physical and chemical methods, wet chemical synthesis is considered to be the more desirable method for industrial applications due to its strong controllability of particle size morphology. It utilizes the redox mechanism to change the nucleation and growth process, and thus regulate the size and morphology by modulating the parameters of a reductant, copper source, protectant, concentration, reaction temperature, and pH.…”
