“…14 Different crack-mechanisms such as crack-bridging HNT-matrix fibers, nanotube pull-out, and nanotube breakage were also observed in highmagnification SEM images of the impact fractured surfaces (Figure 13). These crack mechanisms have been accepted to be the reason for the improved ductility and impact resistance since they absorb extra energy, 14,[42][43][44][45][46] which confirm our findings in the impact test.…”

Polypropylene (PP)/maleic anhydride grafted polystyrene-b-poly (ethylene/butylene)-b-polystyrene (SEBS-g-MA)/organophilic halloysite nanotube clay ternary nanocomposites were produced by using HNT/SEBS-g-MA masterbatches at different nanotube loadings (1 wt%, 3 wt%, and 5 wt%). The masterbatches with different ratios of HNT/SEBS-g-MA (1/1, 1/2, and 1/3) were prepared via a revolution/rotation type mixing-assisted masterbatch process. All nanocomposites showed higher storage moduli and damping at low temperatures as compared to neat polypropylene. The nanocomposites having HNT/SEBS-g-MA ratio of 1/3 were found to act as effective dampers with their relatively higher damping values. In terms of short-term creep performance, 1 wt% and 3 wt% organophilic halloysite nanotube loaded systems with low amount of SEBS-g-MA (<9 wt%) enhanced dimensional stability of polypropylene with their lower creep strain and permanent deformation values. More specifically, among the nanocomposites, 3 wt% organophilic halloysite nanotube loaded nanocomposite with HNT/SEBS-g-MA ratio of 1/3 and co-continuous like morphology not only exhibited an effective damping over a wide range of temperature (from −70℃ to 50℃) but also showed relatively higher storage moduli at low temperature region together with lower permanent creep deformation as compared to neat polypropylene. As a result, the HNT/SEBS-g-MA masterbatch in 1/3 ratio was found to be the most suitable in polypropylene blend nanocomposites. It may be advantageous for polypropylene nanocomposite based applications where high damping/toughness at low temperature conditions and high dimensional stability under load are desired.

Polypropylene (PP)/maleic anhydride grafted poly(styrene-b-ethylene-co-butylene-b-styrene) triblock copolymer (SEBS-g-MA)/halloysite nanotube (HNT) ternary nanocomposites were prepared by two methods: onestep simultaneous melt mixing (SM) of all components; and masterbatch-based melt mixing (MB) involving revolution/rotation-type high shear mixing of a concentrated solution of HNT and SEBS-g-MA, followed by melt blending with PP. Organically modified HNTs (Org-HNTs) with cetyltrimethyl ammonium bromide were prepared via a special cryoscopic expansion/modification technique (C-XP/M). The morphological structures and mechanical properties of the composites, as well as the amount of reinforcer/toughener-compatibilizer (HNT/SEBS-g-MA) at a ratio of 1/3, were discussed as a function of SM and MB techniques. Morphological studies showed that the SM technique revealed microcomposite structures with large aggregates of Org-HNTs in the matrix. In contrast, the MB technique, with the help of elastomeric phase encapsulation, resulted in the best HNT dispersion in the PP matrix, leading to improved mechanical properties. In particular, the PP-based ternary nanocomposite with 3 wt % Org-HNT and 9 wt % SEBS-g-MA prepared by the MB method exhibited 200% higher impact strength compared with PP, attributed to well dispersed, encapsulated, and compatibilized HNTs in the matrix, which created a good balance between stiffness and toughness.

Polymeric nanocomposites are the materials incorporating nanosized inclusions into the polymer matrixes. The result of the addition of nanoparticles/fibers is a drastic improvement in properties that may include mechanical, electrical, thermal conductivity, or even the acoustical properties. Polymer nanocomposites have spawned huge interest for the development of high‐performance products such as lightweight sensors, thin‐film capacitors, batteries, flame retardant products, biodegradable and biocompatible materials, and so on. The field of polymer nanocomposites has been at the forefront of research in the polymer community for the past few decades and an extremely large number of scientific papers have been published. Nevertheless, application‐oriented guidelines for selecting the ecofriendly nanocomposites for advanced industrial applications are missing in the state of the art. This review article summarizes the current state‐of‐the‐art polymeric nanocomposites, highlighting prominent nanofillers categorized based on their applications, origins, dimensional characteristics, and so on. Each filler type contains a short description of its main feature together with the most relevant and potential applications. To address the global concern about nondegradable wastes, novel green alternatives of each nanofiller type are discussed. Special attention is also given to the biocompatibility properties of the composites. This study provides a state‐of‐the‐art road map to select multifunctional polymeric nanocomposites from huge varieties for advanced industrial applications.
