Remote Plasma Device for Surface Modification at Atmospheric Pressure

Here, a novel atmospheric plasma device is presented, which applies the (remote) afterglow of micro-barrier discharges. The study evaluates its applicability to surface modification of temperature-sensitive particulates. As such, cylindrical samples have been placed in the remote treatment zone of the device, and the effects of treatment time and variable gas mixtures on the surface wettability are investigated. Furthermore, the influence of the excess voltage in He discharge with admixtures of O2, CO2 and N2 and the effect thereof on the water contact angle is described.
