Influence of different types of surfactants on electrodeposition of copper- and carbon-bearing (graphite, carbon nanotubes (CNTs)) composite powder has been experimentally investigated. The size of powder particles decreased, and corrosion resistance increased when surfactants were added. Addition of cationic surfactant CTAB to the electrolyte with simultaneous ultrasonic treatment for CNTs dispersion gives maximum effect.
The article presents the results of studies of electrochemical deposition of silver nanoparticles (AgNPs) on the silicon surface in dimethylformamide solutions of 0.025M; 0.05M; 0.1M (NH4)[Ag(CN)2]. Combination of a pulsed electrolysis mode and an organic aprotic solvent medium (DMF) ensures the formation of 50-150 nm spherical AgNPs with uniform distribution over the silicon surface. It is shown that the main factors influencing the morphology and size of silver nanoparticles are the value of the cathode potential, the concentration of ions [Ag(CN)2]- and the duration of electrolysis.
