    Characterization of crystalline quality of diamond films by Raman spectroscopy (1989)

    Notes: We have measured Raman spectra of diamond films prepared by a hot-filament method and found that diamond layers on Si substrates are under compressive strain. The degree of the strain is found to increase with increasing nondiamond component in the diamond films. It is shown that Raman spectroscopy is a powerful method to estimate the crystalline quality, especially the strain in the diamond films.

    Raman spectra of diamondlike amorphous carbon films (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 64 (1988), S. 6464-6468

    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Raman spectra of diamondlike amorphous carbon (a-C) films prepared under atmosphere with various hydrogen gas content have been measured as a function of excitation wavelength. The Raman spectral profiles vary with excitation wavelength depending on electronic absorption spectra associated with π-π* electronic transitions. Dependence of Raman spectra on excitation wavelength is interpreted in terms of π-π* resonant Raman scattering from aromatic rings with various sizes rather than polyene chains. The relative intensity of a 1400 cm−1 band against a 1530 cm−1 band is found to decrease with an increase of sp3 content in a-C films. It is shown that the relative intensity can be used as a parameter for sp3 content.

    Resonant Raman scattering of diamondlike amorphous carbon films (1988)

    Notes: Raman spectra of diamondlike amorphous carbon (a-C) films prepared by the sputtering method have been measured as a function of the excitation wavelength. The Raman spectral profiles vary sensitively, reflecting the change of absorption spectra associated with π-π* electronic transitions with the hydrogen content of the films. From a comparison between Raman and electronic absorption spectra, it is confirmed that the Raman spectral variation with the excitation wavelength is due to the π-π* resonant Raman scattering from π-bonded (sp2) carbon clusters.

    Dynamic-mechanical properties of interfacially modified glass sphere filled polyethylene (1988)

    Notes: Abstract Model composites of spherical glass particles dispersed in a matrix of high density polyethylene were prepared both with and without interfacial modification by an azidofunctional trialkoxysilane. Dynamic mechanical measurements of the composites in the melt state were recorded. The unmodified composites behave as theoretically predicted and the effect of particle—particle interaction at high volume fractions can be measured. The composites with a modified interfacial region have greater shear moduli due to the effect of a region surrounding the particle modified by the silane. The material in this region is largely bound to the glass surface and was examined by Fourier transform infrared spectroscopy after extraction of the bulk matrix. Theoretical calculations are shown to be useful in calculating the mechanical properties and volume fraction of the interfacial region.

    Interfacial effects on the melt state behavior of polyethylene-EPDM-calcium carbonate composites (1988)

    Notes: Abstract Dynamic mechanical spectra of various composites of high density polyethylene (PE), ethylene propylene diene rubber (EPDM), and calcium carbonate were obtained at 190°C with a parallel plate instrument. Interfacial effects were found to have a significant influence on the dynamic mechanical behavior of these composites. Composites of calcium carbonate in PE displayed prominent particle—particle interaction effects. This resulted in a greatly enhanced dynamic shear modulusG d due to the filler addition. Treatment of the calcium carbonate with gamma-aminopropyltriethoxysilane (γ-APS) or gamma-methacryloxypropyltrimethoxysilane (γ-MPS) significantly reduced the particle—particle interactions. Solution deposition of EPDM or EPDM grafted with maleic anhydride (EPDM-MA) on the calcium carbonate, before incorporation into a PE composite, also had a significant effect on the composite properties. Comparison of data from composites treated with EPDM vs. EPDM-MA suggested the presence of an interaction between the calcium carbonate surface and the maleic anhydride modification. This conclusion was further supported by solid state proton NMR relaxation model experiments which showed significant immobilization of the EPDM-MA chains on the filler surface. The treatment of calcium carbonate withγ-APS orγ-MPS before incorporation into multicomponent polyethylene-rubber-filler composites also had a significant influence on the dynamic mechanical properties of the resultant composites. There is evidence for a reaction betweenγ-APS and EPDM-MA during processing on the roll mill.

    Description / Table of Contents: Die Reaktion zwischen Polyvinylpyridinen und Epoxyverbindungen wurde sowohl in homogenen Lösungen als auch im festen Zustand mit Hilfe der Fourier-Transform-Infrarotspektroskopie und anderer Techniken untersucht. Es wurde beobachtet, daß die Pyridinseitengruppe mit den Epoxygruppen unter Bildung von Netzwerken, die Pyridon- und cyclische Amidstrukturen enthalten, reagiert. Diese Reaktion wurde ebenso in der Grenzflächenregion zwischen Polyvinylpyridin und Überzügen aus γ-Glycidoxypropyltrimethoxysilanhydrolysat auf Poly(ethylenterephthalat)-Fasern beobachtet.
    Notes: Chemical reactions of poly(vinyl pyridine)s and epoxy compounds were studied both in homogeneous solution and in solid state by Fourier transform infrared spectroscopy and other techniques. The pyridine side group was found to react with the epoxy group, forming networks which contain pyridone and cyclic amide structures. This reaction was observed also in the interfacial region of poly(vinyl pyridine) and γ-glycidoxypropyltrimethoxysilane hydrolyzate coatings on poly(ethylene terephthalate) fiber substrates.
