Abstract:
A method for plasma treatment in hollow bodies, comprising:providing a hollow body which has an opening and which is at least partially flexible;evacuating the hollow body with volume contraction to a first pressure which is preselected such that the hollow body after evacuating and sealing, experiences a volume expansion in the region of a second pressure, by means of which volume expansion the pressure in the hollow body assumes a value which allows ignition of a non-thermal gas discharge in the hollow body;gas-tight sealing the hollow body while maintaining the first pressure;introducing the hollow body, after evacuating and sealing into a vacuum chamber;evacuating the vacuum chamber to the second pressure; andigniting a gas discharge in the hollow body after sealing by application of an electrical field.
