Abstract

Abstract : An atmospheric argon plasma jet has been used to explore the plasma penetration inside tubes of small diameter and the plasma treatment effect on the inner tube surface. The goal of this paper is to show how the tube size can influence the plasma jet penetration and the resulting surface effects on polyethylene tubes with diameters varying between 0.28 mm and 3.00 mm. Optical emission spectroscopy and light emission images have been used to investigate the distribution of active species along the tube length. To examine the plasma treatment effect on the inner tube surface, capillary action, water contact angle measurements and XPS analysis have been used. The results presented in this paper will clearly demonstrate the great potential of atmospheric pressure plasma jets for inner tube surface modification. Abstract : Plasma penetration of an atmospheric pressure plasma jet inside tubes of different diameters is investigated. Plasma treated samples are examined by XPS and water contact angle measurements along the tube length to determine the dependency of treatment effect on tube size and exposure time. Additional useful information is obtained from studying light emission images and capillary effects.
