Scientists at University of California release new data on plasma science

  2009 JUL 7 - (VerticalNews.com) -- According to recent research from the United States, "MD simulations of ion-organic styrene-containing polymer interactions are reviewed and compared to experiment."

  "We report results for argon ion bombardment of PS, P alpha MS and P4MS. All three polymers exhibit the formation of a similar, highly cross-linking, dehydrogenated near-surface damaged layer at steady state, but small changes in the structure of the polymer (P4MS and P alpha MS are isomers) can lead to drastic changes in the initial transient sputtering of the material," wrote J.J. Vegh and colleagues, University of California.

  The researchers concluded: "We correlate this behavior to differences in radiation chemistry (P4MS and PS are cross-linking while PaMS is a chain scission polymer), and examine how the behavior in MD may relate to larger-scale experimental results, such as roughness formation."

  Vegh and colleagues published their study in Plasma Processes and Polymers (Molecular Dynamics Simulations of Ar+-Organic Polymer Interactions. Plasma Processes and Polymers, 2009;6(5 Sp. Iss.):320-334).
