Abstract
In this work, plasma discharge in the liquid phase under the action of intensive ultrasonic cavitation has been applied to synthesize zinc oxide nanoparticles. The resulting nanoparticles were characterized by the range of methods of physicochemical analysis − dynamic light scattering, scanning electron microscopy, and X-ray phase analysis. It was shown that the particles had rod-like shape with size about 40 nm, a narrow size distribution, and were stable to aggregation and sedimentation. The values of ε-potential of the particles surface were measured when interacting with a water-soluble polymer.
