“…In the other words, the number of the extracted PC particles with a diameter of 750-1000 nm was maximum in the case of P80C10N5 sample, whereas the maximum was observed at the extracted PC particles with a diameter of 500-750 nm in the case of P80C10N10 sample. This observation can be related to the fact that NC addition increases the shear tension and the melt viscosity of polymers, prompting the possibility of droplet breakup, which was reported in our previous work [35]. Even at low NC content ( Figure 7A and C), there is a significant effect of NC on the size distribution of PC phase.…”

Polypropylene/polycarbonate (PP/PC) nanocomposites containing various proportions of the organically modified montmorillonite were prepared by extrusion and injection molding process. The morphology of PP/PC nanocomposites was characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The nanocomposites with 3 or 5 wt% of nanoclay (NC) show a uniform dispersion of the NC as pointed out by two different methods, TEM and XRD. It was shown that the morphology of dispersed phase (PC) is highly dependent on the content of minor phase, which was correlated with the balance of drop breakup and coalescence. The mechanical properties have been investigated by tensile test and Izod impact test. The virgin PP/PC samples showed a reduction in impact strength and elongation at break and up to 50% increase in Young's modulus by increase in PP content comparing with the pure PP. Investigating the effect of NC and PC content on the mechanical behavior of PP/PC nanocomposites showed increased Young's modulus and decreased impact strength with increasing PC and NC loading. An obvious ductile to brittle behavior transition at a high content of PC or NC was supported by notched Izod impact strength experiments and SEM results.

“…9 corresponding to the basal spacing of 31.5 Å . The leftward shift observed in the peak position of elastomer nanocomposite samples containing 3, 5, 7, and 10 phr Cloisite 15A compared to that of pristine clay is ascribed to an increase in the intergallery spacing of clay silicate layers, which could indicate the intercalation of polymer chains into the silicate galleries.…”

“…They attributed the lower stiffness observed for organoclay nanocomposites to the lower volume fraction of filler compared to the commercial tire treads. Esmizadeh et al [9] determined that there were modified model parameters fitting experimental measurements with several hyperelastic models.…”

Micromechanics of elastomer nanocomposite samples based on polybutadiene (BR), ethylene‐propylene diene terpolymer (EPDM) hyperelastic matrixes prepared via melt compounding was investigated using uniaxial tensile analysis. Constitutive hyperelastic models, including Polynomial, Yeoh, Ogden, Arruda‐Boyce, and Van der Waals were used to determine material parameters in incompressible isotropic elastic strain‐energy functions on the basis of a nonlinear least squares optimization method by fitting the data obtained from uniaxial classic experiments. Effect of nanoclay (0, 3, 5, 7, and 10 phr) content on the simulation accuracy was investigated. Simulation results compared with the experimental data suggested that the Ogden model as the most consistent model investigated here. J. VINYL ADDIT.

“…Fluorosilicone rubber (FSR), which is well known for excellent oil and fuel resistance in a wide operating temperature range (260 to 200 8C) has found wide application in automotive and aircraft industries, petroleum-related equipments, and so on.

The thermal aging behavior of poly(3,3,3-trifluoropropyl)methylsiloxane was investigated by thermal gravimetric analysis and isothermal aging tests, and the results indicated the degradation mechanism II, oxidation scission of the side groups, played a more important role when the temperature was below 350 8C. The addition of ceria had significantly improved the thermal stability of fluorosilicone rubber (FSR) by inhibiting the oxidation scission. Moreover, two types of ceria including laminar-structure ceria (LS-CeO 2 ) and nanoparticle ceria (N-CeO 2 ) were prepared and surface was modified by KH570 and characterized by scanning electron microscopy, transmission electron microscope, and X-ray diffractometer. FSR incorporated with modified LS-CeO 2 and N-CeO 2 revealed a significant improvement on the heat resistant properties. In particular, after having been thermal oxidative aged for 70 h at 250 8C, FSR containing 2 wt % of modified N-CeO 2 maintained 72.6% of tensile strength and 63.9% of elongation at break, respectively, while FSR without ceria completely failed.
