Bentonite clay is surface modified and incorporated into PC/ABS (70/30) polymer blend by melt mixing in concentrations of 1, 3 and 5 wt% of clay. The efficiency of the treatments is analyzed by Fourier transform infrared spectroscopy (FTIR), x‐ray fluorescence (XRF) and x‐ray diffraction (XRD). Differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) are used to evaluate the blends miscibility and morphology, respectively, and the mechanical behavior is analyzed by tensile tests. The methodologies used are efficient to modify the clay's surface. DSC and SEM showed that the blend remained immiscible with the addition of the fillers. The mechanical test showed an increase in the Young's modulus of the nanocomposite with addition of 1 wt% of the natural clay and a modification in the fracture behavior of the blend, from ductile to brittle, when 3 and 5 wt% of the organophilized clay are used.

“…Similar to the observations made by Mirmohseni and Zavareh, the disappearance of the ABS nanocomposites diffraction peaks indicated the possibility of exfoliation of the nanoclay platelets due to crystallographic loss. In addition, the disappearance of the peak may have resulted from the disordered orientation arrangement of platelike particles, such as muscovite in a polymeric matrix of composites.…”

In this research, we investigated the mechanical and thermal properties of acrylonitrile–butadiene–styrene (ABS)–clay nanocomposites and correlated them with morphological characterizations. We prepared nanocomposites of ABS–clay by melt compounding in a Haake internal mixer. In this study, we investigated the influence of the ion‐exchange process and clay loading on the nanocomposite structure and characterized the nanocomposites with wide‐angle X‐ray diffraction (WAXD), transmission electron microscopy (TEM), contact angle measurement, field emission scanning electron microscopy (FESEM), tensile properties, hardness testing, and thermogravimetric analysis. The ABS–organomuscovite nanocomposites in this study displayed a higher tensile strength than ABS–muscovite. The modified muscovite indicated a 13% modulus elasticity in the ABS nanocomposites, whereas the elongation at break was detrimentally affected compared to that of the neat ABS. The WAXD and TEM results show the presence of mixed intercalated and exfoliated structures. FESEM analysis further revealed a good dispersion and interfacial adhesion of clay layers after subsequent modification. The contact angle measurements showed that the incorporation of organoclay was able to improve the hydrophobicity of the ABS nanocomposites. Finally, the hardness and thermal stability of the nanocomposites improved with the incorporation of modified muscovite. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46827.

“…However, stricter thermal and flame-retardant performances are often required, and the addition of inorganic compounds appears to be one promising route for applicative research in composite materials [11][12][13][14][15] in terms of achieving applicative needs. Thus, many studies have been reported in the last decade on PC doped with triazole stabilizers and additives dispersed as microparticles [16][17][18][19][20] and, more recently, with noble metal nanoparticles (NPs) [21].…”

Prediction of Thermal Behavior of Polycarbonate/Cerium Oxide Composite Films

Thermal effects in polycarbonate (PC) induced by lanthanide oxide nanoparticles (NPs) dispersed by blending were studied using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). DSC data proved the occurrence of solvent-induced crystallization of polymer doped with cerium oxide (ceria). TGA was performed to predict PC flammability properties in composites with 5-15 wt % ceria NPs at various heating rates. Decomposition was represented by first-order reactions and the Arrhenius equation. A model was formulated for thin samples subject to uniform heat irradiation, which is based on PC softening and decomposition into several products. This is an attempt to predict composite film burning behavior assuming constant heat transmission to samples.
