“…TEM showed partial exfoliated structure of silicate layers disposed through both NBR and PA6 phases. DSC data showed that loading of the nano clay reduced the degree of crystallinity and improves the Young's modulus (83,84).…”

Blending polymers is used to obtain products with improved and wider range of properties. A polymer blend or polyblend is a microscopically mixture of two or more polymers. This paper deals with polyblend nanocomposites where one of the components has at least one dimension of the order of nanometer. It covers different groups of nanocomposites depending on the type of the polymer used in such mixtures, mainly:thermoplastic -thermoplastic polymer blend nanocomposites, thermoplastic -thermoset polymer blend nanocomposites, thermoplastic -elastomer polymer blend nanocomposites, biodegradable polymer blend nanocomposites.

“…Table 2 depicts the rising trend of hardness with increasing the clay content. This phenomenon could be ascribed to the strong interactions established between the elastomer chains and silicate layers as well as the nanoclay hardness [17] . The development of abrasion resistance caused by the formation of a filler network within the rubber matrix is illustrated in Table 2.…”

“…Observed peaks are also intensified with increasing the clay loading from 3 up to 10 wt % . Thus, it is understood that the agglomerated clay layers are more probable to form within the nanocomposites containing higher clay contents; such systems would consequently require higher stress values to obtain a well dispersed nanocomposite [17] .…”

Ternary elastomer nanocomposites based on acrylonitrile butadiene rubber (NBR), polybutadiene rubber (BR) and two types of nanoclay (Cloisite 15A and Cloisite 30B) were prepared using a laboratory scale tworoll mill. The effects of nanoclay composition on the cure characteristics, mechanical properties and morphology of NBR/BR (50/50) nanocomposite samples containing 3, 5, 7 and 10 wt % nanoclay were investigated. According to the cure characteristics both types of nanoclay caused a reduction in the scorch time and optimum cure time of the nanocomposite compound. X-ray diffraction patterns of all samples suggested the intercalation of polymer chains into the silicate layers. This was confirmed by transmission electron microscopy (TEM) micrographs. Dynamic mechanical thermal analysis (DMTA) was utilized to study the dispersion state of nanoclay within the elastomer blend matrix. The results showed the development of mechanical properties with the establishment of interactions between nanoclay and polymer chains. Antiknock and brake fluid uptake were also reduced with increasing the nanoclay content.

Albeit, it was shown that if a thermodynamically stable state is V C 2013 Wiley Periodicals, Inc. reached, increasing the residence time in a constant shear rate does not affect the nanoclay dispersion.…”

“…6 Fornes and coworkers 7,8 studied the effect of the molecular weight of the polymer matrix on the exfoliation process. On the basis of the knowledge developed in previous studies, 14,18 we paid attention to infer the alteration of the ultimate properties on the basis of the interlayer distance of the nanoclay and the rubbery-phase particle size. They reasoned this observation on account of the higher shear stress induced by the increase in the melt viscosity.…”

Applying the Taguchi method of experimental design, we prepared various polyamide 6 (PA6)/acrylonitrile butadiene rubber (NBR)/nanoclay nanocomposites under different processing conditions by melt mixing in an internal mixer. The effects of the processing variables, including the rotor speed, chamber temperature, and mixing order on the morphology, that is, the rubber particle size and interlayer distance, and the mechanical properties, that is, the tensile modulus and impact strength, were then investigated. As demonstrated with the Taguchi approach, the lower temperature associated with higher rotor speeds improved the mechanical properties of the 90/5/5 PA6/NBR/nanoclay systems. However, it was revealed that the mixing order did not affect the mechanical properties for the assigned composition. Hence, the simultaneous mixing of all the ingredients is seemingly the simplest way of mixing to obtain the desired mechanical properties. These results were confirmed with transmission and scanning electron microscopy observations and X-ray diffraction measurements. Image analysis corresponding to the mean particle size of the NBR constituent was also performed. The optimum processing condition to achieve the appropriate mechanical properties is ultimately predicted by the Taguchi analysis and corresponded to a chamber temperature of 230 C and a screw speed of 80 rpm. Moreover, the simultaneous mixing of all of the ingredients was suggested for convenience.
