| Description | A method of plasma treatment of an internal and/or external surface of a hollow electrically non-conductive body. The internal surface of the body and/or its external surface acts a layer of electrical plasma of a surface dielectric barrier discharge generated in a volume of gas by alternating or pulse voltage with an amplitude higher than 100 V from a pair of liquid electrodes formed by an internal electrically conductive liquid situated inside the body and by an external electrically conductive liquid situated outside the body. The electrical plasma is generated above the surface of the electrically conductive liquid, where in the volume of the gas forms a layer of electrical plasma forming a ring copying the shape of the surface of the body wherein the electrical resistance between the liquid electrodes is greater than 10 kOhm. The invention also is a device for carrying out the aforementioned method. |
