Article Synopsis
- - The plasma jet transfer technique utilizes a conductive wire at floating potential to ignite a plasma plume inside a flexible tube for surface modification of polypropylene (PP) samples using argon gas.
- - Two configurations were tested: one with a thin copper wire directly in the gas flow and another with a metallic mesh that creates a dielectric barrier between the plating and gas.
- - Water contact angle (WCA) measurements indicated that the distance between the jet outlet and the PP surface influences the effectiveness of the surface modification, with XPS analysis revealing a relationship between WCA values and the formation of oxygen-functional groups.
