“…The correlations between the shape of loaddisplacement curves, the nature and features of fractured surface, the mode of crack growth and finally the macroscopic deformation behavior of the samples are also presented in this figure. The same multiple deformation zones at the front of crack tip on the fracture surface during crack growth have been observed by the other researchers for ABS composites [40,46] and other toughened systems [10,47,48] Effect of blend composition on bulk deformation. The structure of the fracture surface and the stress-whitened zone provides useful and direct information with regard to the deformation mechanisms that occurred and the stability of the propagating crack upon loading.…”

A linear elastic fracture mechanics (LEFM) approach was used to study fracture characteristics of ABS materials. The effects of crack (ligament) length and rubber content on the microscopic deformations taking place at the front of crack tip and in the bulk of the specimens were investigated. The results of fractography studies showed that, in addition to rubber content, the microscopic deformations are influenced by crack length. For some materials this manifests itself as a change in macroscopic response. The ligament length dependent behavior was increased for the samples with higher rubber contents. The results also showed that, although the elastic behavior with unstable crack growth is the dominant micromechanism of deformation, stable crack propagation still occurred in some compositions. All the fracture parameters, including fracture toughness, fracture energy, plastic zone size, and crack tip opening, increased with rubber content. The changes in microscopic and, as a consequence, in the macroscopic deformation behavior of a given specimen with ligament length were attributed to changes in yield stress of the sample and maximum stress on the ligament.

“…Figure 8 shows the SEM micrographs of the blank, C2, C15, C30, T2, T5, and T30 samples. The SEM micrograph of the blank sample shows that BR particles formed spherical particles and holes 20. By viewing the SEM micrographs of the freeze‐fractured surfaces of the samples, we could see that both TiO 2 pigments had no effect on the size of the BR particles.…”

Titanium dioxide (TiO 2 ) pigments may be surface-modified by hydrous oxides, such as alumina (e.g., Cristal 134) or by organic compounds, such as organophosphate (e.g., Tiona 188). In this investigation, the effects of these pigments on the rheological properties of acrylonitrile-butadiene-styrene (ABS) polymer were investigated. With the oscillatory rheometry method in the linear viscoelastic region, the storage and loss moduli versus frequency graph of ABS in the molten state showed two crossover points (COPs) when the surface of the ABS components, that is, poly(styrene-stat-acrylonitrile) and poly[(styrene-stat-acrylonitrile)-graft-polybutadiene] or g-ABS, had good interaction. The first COPs increased when the TiO 2 content rose to 0.5 and 1.5% in Tiona 188 and Cristal 134 pigmented ABS samples, respectively. With the addition of TiO 2 up to these contents, the polymer-pigment interaction becomes stronger so that the dispersion of the pigments was good. With increasing TiO 2 , the first COPs dramatically decreased because of agglomeration of the pigments. The shifting of the first COP may be applied as a criterion to specify the dispersion of TiO 2 particles in the ABS matrix. Scanning electron micrographs showed that the pigments had no effect on the size of the polybutadiene particles. Also, transmission electron micrographs proved that agglomerates of Tiona 188 and Cristal 134 particles were formed above 0.5 and 1.5% TiO 2 contents, respectively. V C 2011 Wiley Periodicals, Inc.

“…Hence, this work involves the fabrication of PMCs with varying compositions using varieties of polymer matrices and carbonous fillers with variations of volume fraction, particle size, morphology, and so forth, and the study of correlations between their viscoelastic and structural properties. The variations of filler types, weight fractions, and so forth have been studied by using acrylonitrile‐butadiene‐styrene (ABS) as the polymer matrix owing to its superior mechanical performance and good electronic and thermal conductivities, making the polymer suitable for the structural applications and for the packaging of electronic accessories. Similarly, to study the effect of the filler particle size and volume fraction on the interfacial interaction, carbon black (CB) of varying particle sizes have been used.…”

Polymer matrix composites reinforced with carbonous fillers are of significant commercial importance thanks to their vast application base. As the performance of such composites largely depends on matrix-filler interaction, the present study is focused on the impact of surface chemical states of polymer matrix and carbonous filler on the viscoelastic performance of the composites. Here we report investigation of the filler-matrix interface through spectroscopic techniques such as X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. Viscoelastic properties of various polymer matrix composites prepared by varying the filler volume fraction and/or the matrix/filler type have been studied through dynamic mechanical thermal analysis. Further, to understand the matrix-filler interaction, correlations between viscoelastic parameters and various structural parameters such as the surface area of filler and the surface chemical states of filler/matrix obtained through XPS have been studied. Strong correlations between the viscoelastic parameters and the matrix/filler surface chemical states have been observed, suggesting the XPS as an important tool to study the role of the surface functionalities present on the matrix/filler surface to define the matrix-filler interaction. The filler surface functionalities such as C bound O have been found more compatible with the polymers having aromatic ring in the repeat unit.The matrix-filler interaction in PMCs is affected significantly by the structure of polymer matrix and the surface characteristics such as area, roughness, and chemical state of filler. 14-17 Among these, the surface structure of fillers, affecting their dispersion, wettability and agglomeration tendency, governs the overall matrix-filler interaction largely. 14,[18][19][20][21][22][23] Presence of surface functional groups has been reported to modify the wettability of the filler, an important parameter determining the matrix-filler Additional Supporting Information may be found in the online version of this article. † Deceased on 08-08-2016.
