“…The Payne effect will be higher, the greater is the value of ∆G´, meaning a higher amount of filler-filler interaction [22]. On the other side, the smaller the filler-filler interaction, the better the filler particles are dispersed [23][24][25][26]. The results Figure 6 confirmed, the filler-filler interactions are aggravated with increasing amount of alternative carbon-based filler.…”

Instead of conventional carbon black, an alternative carbon filler (ACB) obtained in the pyrolysis process from tire waste was used for rubber compounds. The fillers were characterized using FTIR and TGA methods. The mechanical properties of the obtained rubber compounds and the influence of the fillers used on the vulcanization process, as well as the Payne effect, were examined. The results confirm the possibility of replacing conventional carbon black with an alternative carbon filler in rubber compounds.

In this study, tetraethoxysilane (TEOS)‐functionalized Na‐bentonite incorporated into polysulfone/polyethylenimine (PSF/PEI) membranes were fabricated by phase inversion method for the efficient removal of methylene blue dye. For the preparation of PSF/PEI nanocomposite membranes, silane‐functionalized Na‐bentonite and pure Na‐bentonite were used at three different concentrations (0.5, 1, and 2 wt%). The prepared membranes were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, atomic force microscopy, porosity, hydrophilicity, and water permeability measurements. Antifouling behaviors and methylene blue dye rejections of the PSF/PEI nanocomposite membranes were also tested. The obtained results showed that the addition of pure Na‐bentonite and silane‐functionalized Na‐bentonite both increased the water permeability of the membranes. The PSF/PEI membrane containing 2 wt% silane‐functionalized Na‐bentonite showed the highest water flux of 105 L m−2 h−1, while the lowest water flux of 1.2 L m−2 h−1 was recorded for pure PSF membrane. Filtration results demonstrated that the antifouling capacity was significantly increased due to the negatively charged surface of the newly generated silane‐functionalized Na‐bentonite PSF/PEI membranes. In summary, TEOS‐functionalized Na‐bentonite can be used to fabricate PSF/PEI nanocomposite membranes with effective filtration ability, antifouling capacity with lower decay ratio, higher flux recovery ratio, and 99% methylene blue dye removal performance.

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.
