    Fractal Analysis and Simulation of Surface Roughness of Ceramic Particles for Composite Materials (1997)
    Springer
    Applied composite materials 4 (1997), S. 69-81

    Notizen: Abstract An analytical model is presented for the determination of the fractal dimensions of particles which are widely used as reinforcement in nanocomposites. The model is used to characterize the surface irregularity or roughness. It was found that fractal dimensions of both the contour and surface of particles depend only on the relative particles size ratio between secondary particles and subunits. It is proposed that, in practical applications, the fractal dimension of a certain reinforcement particle can be obtained by a combination of this model and a state-of-the-art instrument that can determine the sizes of primary and secondary particles by image analysis. It is possible to relate the fractal dimension with the adhesion and other physical and chemical properties at the interface between particles and matrix.

    A method for the preparation of PMMA-SiO2 nanocomposites with high homogeneity (1996)
    Springer
    Applied composite materials 2 (1996), S. 385-393 
    Details
    ISSN: 1573-4897
    Schlagwort(e): nanocomposites ; poly(methyl methacrylate) ; silica
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau
    Notizen: Abstract It is possible to optimize the performance of the inorganic-organic composites dispersing the inorganic component in the organic matrix on a nanomiter length scale. If dry the inorganic phase cannot be intimately dispersed during the incorporation in the matrix. When the particle surface is organically modified, and the incorporation is made starting from a liquid dispersion (particles in polymer solution), the resulting composites exhibit an excellent homogeneity. Here, monolithic [poly(methyl methacrylate)/monodisperse silica particles] nanocomposites have been prepared and characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), micro-hardness, and differential scanning calorimetry (DSC).

    Erosion of reinforcement particles in SiC/aluminum composites (1994)
    Springer
    Applied composite materials 1 (1994), S. 449-463 
    Details
    ISSN: 1573-4897
    Schlagwort(e): SiC-pure Al composites ; Erosion ; Interfacial reaction ; SEM analysis ; Granulometrical analysis
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau
    Notizen: Abstract The granulometrical and morphological variations of eroded reinforcement particles during annealing for different times at several temperatures have been studied for SiC-pure Al system. The changes produced have been analysed by scanning electron microscope (SEM) after particle extraction.

    Synthesis and characterization of new polymer-ceramic nanophase composite materials (1996)
    Springer
    Applied composite materials 3 (1996), S. 103-116 
    Details
    ISSN: 1573-4897
    Schlagwort(e): nanocomposites ; thin film ; spin-coater deposition
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau
    Notizen: Abstract Optically transparent nanocomposites are of special interest since they have great potential in optical applications. The synthesis of poly(methacrylic methylester)/monodispersed Cu2(OH)2CO3 particles, a new nanocomposite material with a refractive index similar to glass, is here described. The system can be easily deposited on glass plates by spin-coating technology, yielding homogeneous, low-defect thin films of high transparency, that can be used as color filters for liquid crystal displays. Differential scanning calorimetry (DSC), dynamic light scattering (DLS), scanning electron microscope (SEM), transmission electron microscope (TEM), and energy dispersive spectroscopy (EDS) have been used to characterize the composite material.
