Verfahren zur plasmagestuetzten Behandlung der Innenflaeche eines Hohlkoerpers und Verwendung desselben

DE 10035177 A UPAB: 20030923 NOVELTY - Plasma treatment method has a hollow body (5) positioned in an electrical AC field, having a frequency of between 50 and 100 Hz, with a partial discharge within the interior of the hollow body at a gas temperature of below 120 deg. C. USE - The plasma treatment method is used for the internal surface of a dielectric, paraelectric, or ferroelectric hollow body, e.g. for deposition of fluorohydrocarbon layer, a fluorocarbon layer, or a plasma polymer containing silicon, for coating of a catheter guide tube, for treatment of a synthetic blood vessel, or for pipettes and capillaries used for biochemical analysis. ADVANTAGE - The method allows internal coating of hollow spaces with a diameter of less than 50 mm
