Scheme of the experimental setup for the DBD modification used in our experiments: (a) The sample poly(ethylene terephthalate) (PET) covered with a layer of indium tin oxide (ITO) (PET/ITO foil) was placed on a silicone dielectric isolator, which is on the top of a rotating table. The rotation ensures an even and uniform degree of modification of the surface of the sample. The table is placed on the top of a laboratory scissor jack to regulate the distance between the high voltage (HV) electrode and the PET/ITO foil. (b) To connect the bottom electrode to the ground, the rotating table was covered with conductive metal layer (copper tape) and a ground port made of an elastic stainless-steel needle was connected with the grounded metal element.
