Treatments of high-density polyethylene (HDPE) with atomic hydrogen - a surface study — •Torben Schlebrowski, Christian B. Fischer, and Stefan Wehner — Department of Physics, University of Koblenz-Landau, 56070 Koblenz, Germany

The deposition of diamond-like carbon (DLC) films on materials like polymers is a well-established method for substrate surface modification and its refinement. The interaction of atomic hydrogen with polymers in contrast is not well studied, although it is part of the most techniques used for DLC depositions. For a complete description of the carbon deposition process it is inescapable to study this aspect, since the hydrogen is supposed to change and modify the polymeric substrate surface by impinging. Measurements by in situ thermal desorption spectroscopy (TDS) during hydrogen treatment are performed to analyze process products and by atomic force microscopy (AFM) surface changes due to the hydrogen processing are revealed. The contribution shows first results for the interaction of atomic hydrogen with common polymers as HDPE.
