“…They have exceptionally small diameters (several nm) and length ( m m, mm or cm) [39,40]. Furthermore, CNTs have incredibly high aspect ratio (∼10 6 ) and a large surface area (~100 m 2 /g to 1200 m 2 /g), which often allows them to form superior interaction with the polymer matrix [22,25,[41][42][43]. The strength of the sp 2 -C-C-bonds gives CNTs an extremely high tensile strength (∼ 150 to 180 GPa), modulus (∼ 640 GPa to 1 TPa) and elasticity, and remarkable electrical conductivity, thermal (more than 1000°C) and chemical stability [1,3,4,12].…”

“…The greater reinforcement effect has been reported to be given by the material with relatively smaller particle size and larger surface area [45]. Carbon black (CB) is the most widely used and most effective conventional reinforcing filler in the rubber industry because it generally enhances the mechanical properties of various rubbers [6,18,24,27]. However, in addition to its environmental polluting nature, the drawbacks of using CB is that it tends to cause difficult processability due to its relatively larger particle size and high bulk viscosity of most rubber compounds [18,24].…”

“…Therefore, scientific and industrial fields have been focusing on partially or completely replacing CB in rubber formulations with CNTs (single-walled and multiwalled) for the production of carbon-based composites, i.e., CNTs-natural rubber and CNTs-synthetic rubber composites, with relatively excellent properties [6,39]. The extremely small particle size, high specific surface area and aspect ratio of this new class of fillers makes them superior to CB, and makes it relatively easy for them to uniformly disperse in the rubber matrix as individual particles [6,28,41]. The distances between the components of CNTs and the rubber matrix are exceptionally [28]).…”

Carbon Nanotubes - Redefining the World of Electronics

The field of electronics involves complex systems where the active and passive electronic devices are integrated on the rubber substrate, e.g., silicone (Q), which provides, through potting, a strong assembly of these devices on the circuit board. Several other rubbers are employed in the field to strengthen, insulate and seal the components of the electronic machines and instruments, and therefore protect them against damage. These rubbers are typically strengthened and toughened using carbon black (CB). However, due to its noticeable drawbacks, recent research in the field of rubber and electronics has suggested the use of carbon nanotubes (CNTs) as alternative reinforcing fillers to produce electronics rubber composites that do not only have enhanced electrical conductiv¬ity, thermal stability, electromagnetic interference (EMI) shielding, weatherability and insulation properties, but also offer outstanding stretchability, bendability and tear strength under frequent elastic deformation. These performances are similar for both single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) in both the functional and structural composites. Although SWCNTs can result in relatively better homogeneity than MWCNTs, most rubbers often constitute MWCNTs because they are relatively cheaper. The great potential of rubber-CNTs composites being extensively used in the field of electronics is explored in this chapter.

Synergistic effects of rubber band infused graphene nanocomposite on morphology, spectral, and dynamic mechanical properties

et al. 2019

View full text Add to dashboard Cite

Rubber band/graphene (RBG) nanocomposites are formed by infusing graphene nanosheet into a rubber band (RB) and subsequently evaporating the solvent. The RB was first pretreated by soaking in toluene solvent in a mild sonication for 3 h before the swollen RB was immersed in graphene dispersion for different time periods of 12 and 20 h. Employing this technique, graphene nanosheets will be attached in the RB matrix to increase the mechanical properties of these nanocomposites. The peaks shifting of RBG composites noted from Fourier‐transform infrared and Raman analyses due to the stress transfer that indicates reinforcement of the graphene nanosheet. Also, dynamic mechanical testing is most useful for studying the viscoelastic behavior of the nanocomposites, which exhibits increasing storage modulus in the following order, RB < RBG‐12h < RBG‐20h and higher shifting of tan δ peak temperature for RBG‐12h and RBG‐20h. The main factor is due to the introduction of graphene content in the RB matrix. The improvement of RB/graphene composite in terms of their mechanical, electrical, and structural properties demonstrated promising candidates for low heat build‐up materials, improved wear resistance and thermal stability, increase significant gas impermeability, and electricity conductivity.
