“…Galineau et al reported a 20% and 33% increase in the elastic modulus of 4 and 5 wt % nanoclay reinforced polycarbonate and poly(lactic acid), respectively . However, the inorganic material is typically inert and requires specific surface treatments to increase its reactivity and compatibility with the polymer matrix as well as to enable exfoliation. , Moreover, the simultaneous improvement of strength and toughness was only achievable in epoxy nanocomposites and was not applicable to other polymers such as PA6, − PA12, polypropylene (PP), and high-density polyethylene (HDPE) . Nonetheless, considerable research efforts continue to focus on nanoclay reinforced polymers, as Beesetty et al recently reported the fabrication of Nanoclay/HDPE nanocomposites through an additive manufacturing approach, while Abdelwahab et al presented PA6 bio-nanocomposites incorporating biocarbon and nanoclay hybrid systems .…”

Polymer nanocomposites have received tremendous attention over the past several decades; however, they can be challenging to implement without establishing chemical interaction between the nanofillers and the matrix. Poorly suited matrix materials can lead to agglomerations and poor interfacial stress transfer mechanisms, which limits the mechanical performance of the resulting polymer nanocomposites. Here, thermoplastic nanocomposites incorporating aramid nanofibers (ANFs) are studied, and it is shown that the performance of the nanocomposite is highly dependent on the similarity of the matrix with the ANF's chemical structure, indicating that amide−amide hydrogen bonding leads to improved mechanical properties. Aramid nanofibers are initially isolated and used to prepare polyamide (PA6), polyamide−imide (PAI), and polyimide (PI) nanocomposites. Solution-cast ANF reinforced PA6 nanocomposites displayed more than 62% and 27% increase in their tensile strength and elastic stiffness, respectively. Similarly, ANF reinforced PAI nanocomposites exhibited more than 25% and 40% increase in their tensile strength and elastic stiffness, respectively. However, solution-cast ANF reinforced PI exhibited negligible improvement in strength and stiffness. The contrast in the performance of ANFs as nano-reinforcements in these nanocomposites is attributed to the ability of the ANFs to establish amide−amide hydrogen bonding in a PAI and PA6 matrix, whereas such interactions are unavailable in PI. This work shows that the introduction of ANF nanofillers may offer a rapid approach free of preprocessing to improve the mechanical properties of polyamide-based nanocomposites through amide−amide hydrogen bonding, allowing for cost-effective and simplified production of stronger polymer materials.

“…Three compatibilizer (SEBS-g-MA) contents were used (0, 8, and 16 wt%) with different ABS contents (5,15,25,35,40,45,50,55,60,65,75,85, 95, 100 wt%) to prepare binary (PA6/ABS) and ternary (PA6-SEBS-g-MA-ABS) blends ( Table 2) . The compounds were prepared on a Leistritz ZSE-18 twin-screw extruder operating at a screw speed of 125 rpm (L/D = 40).…”

“…Polymer blends based on polyamide 6 (PA6) have gained large attention in industrial applications because they combine excellent mechanical properties and easy processability [15,16]. PA6 has attracted a particular attraction because of a good balance between high strength/stiffness, low friction, and excellent chemical/wear resistance.…”

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.

“…Polymer blend composite (PBC) becomes a core of polymer science and engineering and posse’s greater toughness, modulus, impact resistance and ample temperature range of sound and vibration damping factor. Polymer blend process becomes a vital and prominent method in polymer science and technology to obtain a new polymeric material (De Almeida et al , 2018). But plastic scrap reforming to a commercial product by a simple hot polymer melt blend leads to poor material properties because of high interfacial tension (Morawiec, 2002).…”

Purpose This study aims to reduce the interfacial tension by increasing the better adhesion between different immiscible polymers phases and also to evaluate the mechanical, thermal and thermo-mechanical behavior of the immiscible polymer blends. Design/methodology/approach The polymer blend composite (PBC) was prepared using a twin-screw extruder followed by injection molding. Two different kinds of PBC with compatibilizer (Ethylene-n-Butylacrylate-Glycidyl methacrylate) of varying compositions like polybutylene terephthalate + poly trimethylene terephthalate and polybutylene terephthalate (30% glass filled) + poly trimethylene terephthalate were prepared and material behavior at various test conditions were studied. The effect of glass fiber reinforcement on polymer blend and the interlocking effect by the compatibilizer between the polymer phases were also assessed. Findings Mechanical behavior of PBC was estimated by tensile, flexural and angular impact tests. Likewise, the thermal deflection was studied with the help of heat deflection temperature test. Thermo-mechanical behavior likes storage modulus, loss modulus and loss tangent were studied using the dynamic mechanical analysis test. Morphological analysis was characterized using field emission scanning electron microscopy. Originality/value This in turn makes the process easy to obtain the PBC having inherent mechanical, thermal and thermo-mechanically stable. And, it also enhances the mechanical properties like tensile, flexural and impact strength. Simultaneously, posse’s excellent heat deflection and thermo-mechanical behavior over a temperature range of 35–140ºC at a constant frequency of 5 Hz.
