“…Besides, the appearance peak at 1540 cm −1 (asymmetric stretching of coupled CO group of carboxylate anion) for RB spectrum and a new enhanced spectrum that almost overlapped appear at 1444 cm −1 (CH 2 deformation) is confirmed the vulcanization process containing coagent . The broad range at 3604 to 3285 cm −1 is characteristic of the stretching vibration mode of the O‐H group . The appearance of a peak is at 1650 cm −1 which corresponds to CC bonding .…”

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.

“…The first step is due to the release of physisorbed water molecules, the second one is due to the removal of oxygen-containing groups existing on the basal plane and on the edges of GO sheets (i.e. hydroxyl, carboxylic and epoxide groups) and the third step is attributed to the decomposition of the carbon-carbon skeleton of GO [41,42]. In addition, a residual weight of about 16% was obtained for GO at 700 C, indicating that the most part of GO was burned into volatile gases mostly at high temperature [26].…”

“…This facilitated the stress transfer between the two phases, increased the interfacial adhesion and therefore enhanced the above mentioned mechanical properties of the blend. [ 39 ] The mechanical properties increase for PE/PP/MAPE, compared to PE/PP, was validated by what was observed in Section 3.1, as a finer morphology led to better performance. [ 40,41 ] Moreover, compared to previous studies, [ 25,26 ] this work not only displayed two more mechanical properties (tensile modulus and tensile toughness of compatibilized PE/PP systems) but also showed that a similar increase in tensile strength and elongation at break could be achieved with a smaller amount of compatibilizer.…”

This is the first study to showcase the use of maleic anhydride‐grafted polyethylene (MAPE) to compatibilize polyethylene (PE)‐rich blends, where polypropylene (PP) represents the minor phase. By first mixing PP with MAPE, and then adding PE, MAPE was assumed to be localized at the PE/PP interface. Microscopy analysis confirmed that MAPE led to a remarkably fine PE/PP/MAPE morphology, with PP being uniformly dispersed into PE and having an average diameter 267% smaller than that in the PE/PP blend. According to mechanical and rheological tests, this translated into a 14%, 20%, and 14% enhancement of tensile strength, tensile modulus, and tensile toughness, respectively, as well as a 10% and 20% drop in PE/PP viscosity mismatch and interfacial tension, respectively. Finally, PE/PP/MAPE tensile toughness and elongation at break were greater than those of virgin PP, while PE/PP/MAPE strength and stiffness were similar to the ones of neat PP. Therefore, this study provides industries with the possibility to utilize products rich in PE instead of those made of more expensive PP, while still keeping the level of performance high; hence, creating a paradigm shift in the development of advanced lightweight polyolefin materials with tuned functionalities.
