Abstract: A method of plasma treatment of an internal and/or external surface of a hollow electrically non-conductive body (1), the principle of which consists in that on the internal surface (2) of a hollow electrically non-conductive body (1) and/or on the external surface (3) of a hollow electrically non-conductive body (1) there acts a layer of electrical plasma of a surface dielectric barrier discharge generated in a volume (7, 9) of gas by alternating or pulse voltage (10) with an amplitude higher than 100 V from a pair of liquid electrodes formed by an internal electrically conductive liquid (4) situated inside the hollow electrically non-conductive body (1) and by an external electrically conductive liquid (5) situated outside the hollow electrically conductive body (1). The electrical plasma is generated above the surface (6, 8) of the electrically conductive liquid (4, 5), where in the volume (7, 9) of the gas, there forms a layer of electrical plasma forming a ring (11) copying the shape of the surface (2, 3) of the hollow electrically non-conductive body (1), wherein the electrical resistance between the liquid electrodes is greater than 10 kΩ. The invention also is a device for carrying out the aforementioned method of plasma treatment of the internal and/or external surface of a hollow electrically non-conductive body (1).
