“…In fact, the stabilization efficiency of graphene oxide and, by extension, reduced graphene oxides, is promoted to a great measure by the functionalized materials with the oxygen containing units (hydroxyls and carbonyls) [ 24 , 78 ]. A special range in which graphene filler may be successfully is the polymer waste recycling [ 79 ]. This application is a proof of ability through which graphene acts by retention of oxygenated fragments or low weight molecules that appear during material ageing.…”

This study presents the improved stabilization effects of graphene on a polymer substrate, namely a styrene-isoprene-styrene triblock copolymer (SIS) which creates opportunities for long-term applications and radiation processing. The added graphene has a remarkable activity on the protection of polymer against their oxidation due to the penetration of free macroradical fragments into the free interlayer space. The chemiluminescence procedure used for the evaluation of the progress of oxidation reveals the delaying effect of oxidative degradation by the doubling extension of oxidation induction time, when the material formulation containing graphene is oxidized at 130 °C. The pristine polymer that is thermally aged requires an activation energy of 142 kJ mol−1, while the modified material needs 148, 158 and 169 kJ mol−1, for the oxidative degradation in the presence of 1, 2 and, respectively, 3 wt% of graphene. The contribution of graphene content (1 wt%) on the stability improvement of SIS is demonstrated by the increase of onset oxidation temperature from 190 °C for neat polymer to 196 °C in the presence of graphene and to 205 °C for the polymer stabilized with graphene and rosemary extract. The addition of graphene into the polymer formulations is a successful method for enlarging durability instead of the modification of receipt with synthesis antioxidants. The presumable applications of these studied materials cover the areas of medical wear, food packaging, commodities, sealing gaskets and others that may also be included through the products for nuclear power plants.

“…The crumpled morphology of these particles on the surface is crucial for avoiding GO sheets from restacking due to van der Waals forces while retaining a large surface area. 11,35,36 Figures 8(c) and 8(d) displays SEM and TEM depicts the surface of sample PC/GO generated with 0.20 wt% GO (c and d). The photographs were obtained at magnifications of ×10000 on the sample surface.…”

“…These nanofillers suggest that a higher specific area causes stronger matrix adhesion at the interface, improving the polymer's mechanical characteristics. 35,36 Different nanomaterials, in addition to micro-sized fibers, have been reinforced in multiscale composites in current history to strengthen interfacial contact among composite materials. CNT as a nano-reinforcement was found to improve interfacial contact owing to its robust anchoring outcome.…”

The mechanical and thermal properties of polycarbonate (PC) mixed with graphene oxide (GO) were investigated on an experimental basis in this study. PC composites with GO concentrations of 0.1, 0.2, 0.5, and 0.75 wt% were produced using a compression molding technique. The results showed that 10%, 26%, 55%, and 98% increased tensile strength, respectively, in comparison to PC. The thermo-mechanical test showed the tan δ value of the sample with 0.2 wt% GO reached 149.9°C, indicating a shift of 4.8° in the high-temperature region when compared to pure PC. Other mechanical tests, such as impact strength, elongation at break, and young modulus displayed the ultimate improvement for PC composites with 0.2 wt% GO content, showing that interactions with the PC and enhancements in mechanical and thermal characteristics are owing to oxygen functional groups in pure GO, mainly carboxyl portions. Therefore, the current study offers an exceptional structural characteristic, which makes the PC composite polymer qualified for high-performance composite.
