abstractThe method for producing powder materials, in particular copper powder, by electrolytic deposition from solution with superimposed ultrasound (sonoelectrochemical method) is represented. The factors affecting the dispersion of powders have been analyzed. It is shown that the particle size of the powder can be controlled by changing the reaction parameters. In this case, the most significant impact on the dispersion of the powder have a cathode current density and cycle time of the current pulse. Sonoelectrochemical method allows to produce the copper powder with an average particle size of about 100 nm. The obtained copper fine powders have high antibacterial activity. In a medium containing such powders the growth of Staphylococcus aureus and Pseudomonas aeruginosa is inhibited. Physical and antibacterial properties of copper ultrafine powders |
