“…As mentioned earlier, these results reveal a reinforcing effect of graphene that restricted the movement of the chain section in the RB composites . Also, the decrease in tan δ of the composites indicates a reduction in heat buildup and damping capability of RB systems with graphene loading …”

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.

“…From the k values, we can infer that the solvent‐polymer interaction was lowest for the TT samples, followed by VC and the highest was for OP samples. To conclude, the sorption mechanism of POSS‐NR nanocomposites was close to Fickian nature, which is usually shown by rubbers and semi crystalline polymers .…”

Three types of polyhedral oligomeric silsesquioxane (POSS)—octaphenyl (OP), POSS@TESPT (TT), and MWCNT@POSS (VC)—were incorporated into natural rubber (NR) to fabricate nanocomposites. The transport properties of POSS–NR nanocomposites were studied through solvent diffusion techniques. Diffusion studies were done with toluene (aromatic solvent) and the influence of nanofiller structure, concentration and compatibility with the NR matrix on various diffusion parameters were analyzed. The fillers that have good interaction with the polymer matrix showed the lowest solvent uptake. The network structure analysis revealed that the polymer chains deformed affinely. The effect of fillers on the chain flexibility was also discussed based on mechanical property studies. POLYM. COMPOS., 40:3020–3031, 2019. © 2018 Society of Plastics Engineers

“…Natural rubber (NR) composites with carbon nanotube (CNT) filler have been widely investigated with the main purpose to prepare strong elastic materials with high electrical conductivity. Typically, the addition of CNT could transform NR from electric insulator to conductive material with outstanding flexibility, elasticity and mechanical properties [1][2][3]. However, the optimum electrical conductivity and other related properties of NR/CNT composites are mainly controlled by localization and three dimensional networks of CNTs in the rubber matrix [4,5].…”

Some properties of carbon nanotube (CNT) filled natural rubber (NR) composites were improved by adding an ionic liquid (IL), 1-butyl-3-methyl imidazolium bis (trifluoromethylsulphonyl)mide (BMI). In this work, the CNT and IL (CNT-IL) were mixed with NR by latex mixing method. Cure characteristics, thermo-mechanical properties, Payne effect, electrical conductivity and thermal stability were investigated. It was found that IL (BMI) accelerated vulcanization reactions and reduced scorch time. In addition, Fourier Transform Infrared (FTIR) results confirmed the role of IL in NR composites along with the reaction between CNT and NR molecules. The temperature scanning stress relaxation (TSSR) measurement was used to assess thermo-mechanical properties, and a relaxation peak of IL was found due to interactions of cations and anions in IL (BMI). Furthermore, the Payne effect was used to qualitatively analyze the roles of IL and CNT in three-dimensional CNT networks in the NR matrix. It was found that CNT dispersion was finer in the NR/CNT composites with IL. Furthermore, the NR/CNT-IL composite had higher electrical conductivity and lower percolation threshold concentration than the NR/CNT composite.
