Towards the development of uniform closed cell nanocomposite foams using natural rubber containing pristine and organo-modified nanoclays

Abstract

A closed cell rubber foam, based on a natural rubber (NR)/nanoclay nanocomposite, was produced using a one-step foaming process with compression molding.

Effect of graphene treated with cyclohexyl diamine by diazonium reaction on cure kinetics, mechanical, thermal, and physical properties of natural rubber/graphene nanocomposite foam

“…The elongation at break of NRF/UG3 and NRF/CG3 were similar to that of unfilled NRF. Generally, the elongation at break of NRF composites decreased with increasing filler content due to the rigidity of fillers . However, in our case the addition of graphene particles does not impair the elongation at break of NRF nanocomposites, meaning that it can retain the elastic behavior of NRF product with high tensile strength.…”

“…However, in our case the addition of graphene particles does not impair the elongation at break of NRF nanocomposites, meaning that it can retain the elastic behavior of NRF product with high tensile strength. It can be concluded that NRF/CG3 exhibits high tensile strength while other fillers (such as carbon black [15,16] and organoclay [49,50]) cannot improve tensile strength of NRF composites at the same loading. Moreover, the elongation at break of natural rubber/graphene nanocomposite foam is similar to unfilled NRF product owing to low filler content.…”

“…Some fillers (e.g., calcium carbonate , kenaf powder , and rice husk powder ) can significantly improve tensile strength and compressive stress of NRF only at high filler loading. Nevertheless, some fillers such as carbon black and NRF/organoclay nanocomposites can provide high impact on the properties of NRF. The intrinsic filler factors that effect on the final properties of NRF composites include filler geometry, size and size distribution, content, compatibility, filler‐polymer interaction and the functional group of filler.…”

Thermoplastic vulcanizate nanocomposites based on polyethylene/reclaimed rubber: A correlation between carbon nanotube dispersion state and electrical percolation threshold

“…Despite the fact that plastic waste is far more significant in volume respect than rubber waste, the latter still deserves a great deal of attention because it constitutes one group of materials imposing an environmental threat as they barely degrade by biological methods . Although today's technology development led to growing interest in the application of elastomers in several industries such as foams, electronics and electrical devices, as well as insulators, dampers, and sports equipment, the automobile industry is still the main consumer of rubber products in tires, engine parts, and fuel systems . The annual global production of tires is reported to be about 1.4 billion units .…”

Effect of carbon nanotube on PA6/ECO composites: Morphology development, rheological, and thermal properties

“…3 Since these materials are not vulcanized so they can be recycle and re-shape via a re-melting process similar a thermoplastic materials. [5][6][7] Carbon nanotubes (CNTs) are known as the ideal reinforcing fillers to produce high-performance nanocomposites with excellent mechanical, thermal, and electrical properties 8,9 compared with other fillers such as glass fiber, talc, calcium carbonate, carbon black, and carbon nanofiber.
