“…In all cases, the distribution and affinity of nanoparticles with the system components has a crucial role in the final properties of the materials. [3][4][5][6] Especially for polymer blends, the ability of the nanoparticle to interact with different matrices and acting in their compatibility is one of the main advantages of its use. 3,5 However, in order to obtain an ideal effect, controlling the location of particles into the mixture is extremely important.…”

“…17 As a consequence, these variations can impair the final properties of the material, and the use of nanoparticles is a good alternative to attenuate the respective interfacial stresses that can be generated in the blend. 3,5 The use of C30B nanoclay in polar and hydrophilic matrices is widespread and can act as a thermal and mechanical reinforcement, as well as influence the compatibility of different phases. 18,19 Nevertheless, based on reports in the literature, its addition at different stages of processing may have divergent effects, where in general the dispersion of the nanoparticles is pointed to as the major reinforcement effect.…”

The influence of selective localization of the nanoclay Cloisite 30B on the morphological, thermal and thermo-mechanical properties of biodegradable poly(lactic acid)/poly(hydroxybutyrate) blends was evaluated in this work. For this, different compounds were obtained by adding the filler in a single phase or mixed with the two matrices simultaneously by melting processing. The simultaneous processing leads to a better dispersion of nanoparticles on the blend and generates a more homogeneous polymer interface, but the properties do not increase in relation to those that were processed in separate steps. For the blends obtained in separated steps, the polymeric domains and, consequently, the superficial tension between phases are better controlled by a nanolayer. Thus, the results obtained in this work indicate that better control of the polymeric interfaces can generate a more significant effect on the thermal and thermo-mechanical properties of nanostructured blends than just a good dispersion of the fillers.

“…Phase separation in the blends, due to immiscibility, leads to low mechanical properties because of poor interactions between each phase. These unfavorable interactions lead to significant interfacial tension in the melt state and low interfacial adhesion in the solid state leading to a multiphase morphology [8,9]. Nevertheless, the properties of polymer blends are not only a function of interfacial interaction between the components but also depend on the dispersed phase size and blend composition (general blend morphology), which can be controlled by processing conditions.…”

Blends polyamide 6 (PA6) and acrylonitrile-butadiene-styrene (ABS) were compatibilized with a styrene-(ethylene-butene)styrene triblock copolymer grafted with maleic anhydride (SEBS-g-MA). In particular, the effects of ABS (0-100 wt%) and compatibilizer (0, 8, and 16 wt%) content were studied. The blends were first prepared by twin-screw extrusion, and different specimens were prepared by injection molding. From the samples produced, the effects of blend composition on morphological, mechanical, rheological, and thermal properties are reported. The structural analysis confirmed that the original blend is immiscible but showed some compatibilization when in the presence of SEBS-g-MA. Incorporation of the compatibilizer and ABS showed negligible effect on the melting behavior of PA6. The compatibilized blends showed higher tensile strength compared with uncompatibilized ones. However, Young's modulus decreased with increasing compatibilizer content. The mechanical results were confirmed by rheological measurements in terms of interaction between each components in the blend.

This work is focused on developing a new type of polymer blend to improve the viscoelastic property of methyl methacrylate acrylonitrile butadiene styrene (MABS). A multi‐phase binary polymer blend was prepared by melt mixing in a twin screw extruder with three different weight ratios (10, 20, and 30 wt%) with a dynamically vulcanized alloy consisting mostly of fully cured ethylene propylene diene rubber (EPDM) particles encapsulated in a polypropylene (PP) matrix trade name Santoprene and an engineered styrene based thermoplastic elastomer trade name VDT to enhance the viscoelastic property of the blends. The compatibility and performance of the binary blend were studied by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), Fourier transform infrared (FT‐IR) spectroscopy, nuclear magnetic resonance (NMR), laser microscopy, scanning transmission electron microscopy (STEM) and tensile analysis. The DMA analysis of the samples revealed that the damping performance was significantly increased with the incorporation of the elastomeric phase into the MABS matrix. In addition, the morphological analysis revealed that VDT is more compatible with MABS compared to Santoprene. The NMR and FT‐IR analysis further supported the reason for higher compatibility of VDT and MABS blend. The improvement of the damping properties has been observed with the increased wt % of the VDT and Santoprene in the blends.
