“…During the transient sputtering phase, there is a significantly higher mass removal in the MD results for P α MS relative to P4MS. Experimental beam system studies of Ar + bombardment at various energies (our results at 150 eV for P α MS and P4MS and other authors' results at 500 eV and 1 keV for P α MS76, 80) also show enhanced mass removal for P α MS over P4MS or PS before reaching steady state. This trend seems to be enhanced in our lower energy studies.…”

“…This is close to the ratio reported for our transient MD data in Table 2. Additional studies have provided mass spectrometry data for 1 keV Ar + bombardment of PS and P α MS, showing a monomer yield ratio for P α MS/PS of ∼2:1 or more 76, 80…”

“…The range of possible exposure conditions is enormous and the resulting surface‐alteration effects are correspondingly large. While plasma‐induced surface‐modification phenomena are common in any application that involves polymers exposed to plasmas, and the effects of plasma and ion‐beam exposure of polymer materials have been studied extensively for many years,7–10 the mechanistic details of these modification and degradation processes remain poorly understood. An important goal in controlling plasma‐polymer interactions is to understand the mechanisms of plasma‐induced polymer alteration.…”

MD simulations of ion–organic styrene‐containing polymer interactions are reviewed and compared to experiment. We report results for argon ion bombardment of PS, PαMS 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 PαMS are isomers) can lead to drastic changes in the initial transient sputtering of the material. 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.

Dynamic mechanical analysis (DMA) is a helpful technique in the evaluation of natural fiber composites (NFCs) for investigating the viscoelastic behavior with respect to time, temperature, and frequency and calculating the phase shift. The authors have previously studied the DMA behavior of reinforced composites made of single (mono) and synthetic fibers. In this work, the DMA responses of bio composites, nanocomposites, and hybrid natural fiber composites are compared, and the factors influencing the responses are evaluated. Fiber loading, filler addition, fiber treatment, fiber stacking, and matrix all affect how viscoelastic NFCs behave. Previous investigations have indicated that the ranges for the storage modulus are 2000 MPa to 5800 MPa, the loss modulus is 150 MPa to 450 MPa, and the tan δ is 0.2 to 0.6. The nanocomposite's mesh reinforcement improves the interaction between all of its constituent parts, which raises the storage modulus. More specifically, because of the better component-to-component contact in nano composite, the mesh size of the reinforcement improved the storage modulus. This review study has contributed to a broad understanding of the viscoelastic behavior of fiber composites utilized in automobile, aerospace, building science, housing, textile, and food packaging applications.

“…Ion implantation and sputtering are now widely used in many technological applications. Low energy ion implantation technology1–6 is used, for example, in the case of formation of shallow high‐doped junctions in MOSFET devices or structural modification of polymer films; the implanted ion energy is varied in such cases between a few hundreds of eV to a few tens of keV. Medium ion implantation energies, which may be assumed to range up to hundreds of keV, are widely used in the doping of semiconductors during fabrication of ultralarge‐scale integrated (ULSI) circuits,7 formation of nanoparticles,8 or improving the tribological properties of materials 9.…”

The construction of an experimental apparatus, for investigation of implantation, secondary ion emission and sputtering processes, during irradiation of samples with an ion beam of up to 70 keV energy, is described. The basis of the apparatus is an electromagnetic mass separator equipped with a quadrupole mass spectrometer located in the collector chamber. The computer data acquisition control system makes it possible to perform the experimental measurements with high accuracy and precision. Preliminary results of secondary ion mass spectral measurements, obtained for C, Al, Si and Cu targets bombarded with Ar(+) and Kr(+) ions, are presented.
