Preparation of colloidal solution of copper nanoparticles using cationic surfactant

The technique of chemical synthesis of copper nanoparticles stabilized in the micelles of cationic surfactant, cetylpyridinium chloride (CPC), has been developed. By varying the volume of the reducing agent, hydrazine, at fixed pH values of the reaction environment the optimal conditions for synthesis of copper nanoparticles with a stable size ranging from 40 to 280 nanometers have been found. The copper nanoparticles obtained in these way are of interest for use in such fields as electronics and chemistry. The synthesized copper nanoparticles have been characterized with the aid of scanning electron microscopy (SEM) and UV-visible spectroscopy.
