The Electrophysical Characteristics of Underwater Impulse Discharge Plasma in the Processes of Creating Multifunctional Composites

Underwater impulse plasma can be used for one-stage production of composite polymer materials containing metal oxide nanoparticles. It was found that the electrode sputtering rate and the phase composition of the formed particles depend on the medium in which the discharge burns: water or a polymer solution. The stages of the formation of an underwater discharge impulse were discussed and the discharge parameters were determined, such as the current density, the field strength in the plasma, and the electron drift velocities. The energy distribution channels in the underwater impulse discharge are analyzed, and it is established that about half of the input energy is spent on heating the solution. The totality of the obtained data can be used in the development of technological foundations for the use of pulsed underwater discharges in the industrial synthesis of polymer nanocomposites.

Automated summary

Underwater impulse plasma is used to produce polymer nanocomposites containing metal oxide nanoparticles in one step. The electrode sputtering rate and particle phase composition depend on the medium, either water or polymer solution. The stages of underwater impulse discharge formation were discussed, and discharge parameters such as current density, plasma field strength, and electron drift velocities were determined. Energy distribution channels in underwater impulse discharge were analyzed, revealing that about half of the input energy is used for heating the solution. These findings can be employed in developing technological foundations for industrial synthesis of polymer nanocomposites using pulsed underwater discharges.
