Polypropylene (PP), acrylonitrile butadiene styrene (ABS), and thermoplastic polyurethane (TPU) nanocomposites filled with 5 wt % of two different kinds of commercially available graphene nanoplatelets (GNPs) were prepared. Composites materials were characterized in terms of thermal properties (thermal conductivity and thermal stability) in order to study the effect of different fillers within different thermoplastic matrices. The exfoliation process and the mechanical properties were also investigated. We chose three different thermoplastic polymers (polyolefin, copolymer and elastomer) to cover a wide range of thermoplastic materials and identify a guideline in the use of GNPs for nanocomposite materials. No drastic differences were observed in terms of mechanical properties when the same matrices were filled with different GNPs. Concerning thermal conductivity, it was observed that the GNPs plane dimensions play a crucial role in the increase of conductive properties. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…[24] Hence, addition of suitable coupling agents, modifiers or compatibilizers, or chemical modification of clay into organophilic is essential in the preparation of rubber/clay composites. Various research on rubber/clay composites particularly on NR, [25,54,55,56] SBR, [57,58,59] BR, [58,60,61] and EPDM [13,24,26,52,62] have been carried out in the past and can be found in the literature.…”

In the new era of sustainable developments, various adaptations have been carried out in many industries to revolutionize the quest for sustainable materials as a method to reduce the dependency on petroleum feedstock. One of such inventions focusing on the automotive industries with new concepts of energy automotive such as electric and hybrid cars, as well as the utilization of inorganic materials as a components of polymer composites, which is expected to reduce the demand and utilization of various rubber composites in automotive parts. However, due to remarkable increment of service life and inherent properties, ethylene propylene diene terpolymer (EPDM) has showed the highest consumption in automotive segments and the fastest development rate in the field of polymer modification. Thus, a comprehensive review concerning the development of environmentally friendly EPDM-based composites reinforced by various clay minerals is highlighted and presented in this article. The characteristic of EPDM, including the chemistry, processing, properties, and applications, as well as the current research on various types of rubber/clay composites, EPDM/clay composites, and rubber/bentonite (Bt) composites, is reviewed and reported. In addition, the characteristics, properties, and applications of different types of clay minerals such as layered silicates, Bt clays, and montmorillonites as reinforcement material in EPDM composites are also included. Finally, the drawbacks and challenges in developments of EPDM/clay composites and the existing improvizations through various compatibilization of EPDM/clay composite system such as chemical modification of clays, functionalization using coupling agents, and compatibilization through grafting are discussed by highlighting the important findings.

“…By reducing the size of the reinforcements from micrometers to nanometers, the nanocomposites reinforced with nano-sized particles exhibit superior mechanical, thermal and barrier, and permeability properties [ 2 ]. Recently, the development of rubber-based nanocomposites has attracted great interest and nano-sized fillers such as layered silicates, carbon nanotubes, metal oxides and polyhedral oligomeric silsesquioxane (POSS) nanoparticles have been widely used to prepare them [ 3 ].…”

The effect of octaisobutyl-polyhedral oligomeric silsesquioxane (OIB-POSS) as a nanosized reinforcement on the cure kinetics, crosslinking density, and mechanical properties of styrene-butadiene rubber (SBR) nanocomposites was examined in this study. For this purpose, SBR compounds with various OIB-POSS nanoparticle loadings at 1, 3, and 5 phr were prepared and their results were compared with a reference compound without OIB-POSS. When 1 phr of OIB-POSS was added to the rubber matrix, the elongation at break values and tensile strength of the corresponding nanocomposite increased by 24.1% and 29.2% compared to the reference sample, respectively. The presence of OIB-POSS nanoparticles and their random distribution in the SBR matrix was confirmed by transmission electron microscopy. The crosslinking density of nanocomposites was calculated by the Flory-Rehner method and a decrease was observed with the addition of OIB-POSS nanoparticles. In addition, thermal aging process as 70 °C for 70 h was applied to vulcanized samples. It was noted that the mechanical properties of SBR/OIB-POSS nanocomposites remarkably improved, whereas their crosslinking densities gradually decreased after thermal aging.
