In the framework of this work, a review of the use of a barrier discharge for modifying the surfaces of various polymer products is given. There are various examples of reducing, increasing the wettability angle of modified samples, deforming, smoothing their surface and changing their surface energies.

In the framework of this work, experimental studies of the modification of the surface of polyethylene by low-temperature plasma and liquid electrodes at atmospheric pressure were carried out. For these purposes, a direct current experimental setup was used. The results of modifications in the parameter range are presented: voltage U = 400 … 800V, current I = 0.3 … 0.8A, jet length l = 50mm, electrolyte flow rate G = 6.2ml / s, jet diameter d = 3mm, NaCl concentration 26%. Estimates of the results are given.

This article presents the results of experimental studies of the voltage drop across a jet electrolytic cathode for various lengths of jets of an electrolytic electrode. The analysis of experimental data indicating a change in the conductivity of the jet electrolytic cathode, depending on the length of the jet.

This paper presents the results of the experimental studies of an electric discharge with liquid electrodes. An aqueous solution of NaCl in glycerine was used as liquid electrodes, in the range of discharge voltage parameters Up = 0 ÷ 1.5 kV, currents I = 0.01 ÷ 2 A. The current-voltage characteristics of the discharge were established.
