“…The synthesis of a CNT/alumina hybrid compound has been reported in previous works [5][6][7], where its composites demonstrated good mechanical and thermal properties [8]. It is a well-known fact that CNTs possess great mechanical, thermal, electrical, and chemical properties, and can be used in polymer composites due to their unique structure [9][10][11][12]. However, their lack of dispersibility in a polymer matrix and their tendency to agglomerate with each other always hinder their original performance.…”

Due to the synergistic effect that occurs between CNTs and alumina, CNT/alumina hybrid-filled epoxy nanocomposites show significant enhancements in tensile properties, flexural properties, and thermal conductivity. This study is an extension of previously reported investigations into CNT/alumina epoxy nanocomposites. A series of epoxy composites with different CNT/alumina loadings were investigated with regard to their thermal-degradation kinetics and lifetime prediction. The thermal-degradation parameters were acquired via thermogravimetric analysis (TGA) in a nitrogen atmosphere. The degradation activation energy was determined using the Flynn–Wall–Ozawa (F-W-O) method for the chosen apparent activation energy. The Ea showed significant differences at α > 0.6, which indicate the role played by the CNT/alumina hybrid filler loading in the degradation behavior. From the calculations, the lifetime prediction at 5% mass loss decreased with an increase in the temperature service of nitrogen. The increase in the CNT/alumina hybrid loading revealed its contribution towards thermal degradation and stability. On average, a higher Ea was attributed to greater loadings of the CNT/alumina hybrid in the composites.

“…Natural rubber (NR) is widely used in various fields of national defense and human livelihood, especially in the fields of transportation [ 1 ], shock absorption [ 2 ] and sealing [ 3 ], due to its excellent physical and chemical properties. There is no synthetic rubber that can completely replace the role of NR in production and life.…”

Intumescent flame retardants (IFR) are an excellent solution to the problem of easy combustion of polymers. Still, the negative effect of the addition of flame retardants is the decline of the mechanical properties of polymers. In this context, carbon nanotubes (CNTs) are modified with tannic acid (TA) and then wrapped on the surface of ammonium polyphosphate (APP) to construct a special intumescent flame retardant structure (CTAPP). The respective advantages of the three components in the structure are explained in detail, especially the role of CNTs with high thermal conductivity in the flame retardant system. Compared with pure natural rubber (NR), the peak heat release rate (PHRR), total heat release (THR), and total smoke production (TSP) of the composites proposed with special structural flame retardants are decreased by 68.4%, 64.3%, and 49.3%, respectively, while the limiting oxygen index (LOI) increased to 28.6%. The TA-modified CNTs wrapped on the surface of APP can effectively reduce the mechanical damage caused by the flame retardant to the polymer. To sum up, the flame retardant structure of TA-modified CNTs wrapped on APP can effectively enhance the flame retardant properties of the NR matrix and reduce the negative impact on mechanics caused by adding APP flame retardant.

“…It is a low‐cost and highly adaptable solution, as conventional mixing equipment, such as internal mixers and two‐roll mills, can be used for this process. Even though this process carries the highest risk of graphene agglomeration, it can still create highly effective nano reinforcement 25,39–41 …”

The complex structure of tyres makes them hard to recycle economically; hence, it is crucial to minimize the generation of tyre waste. Nano‐reinforcement, such as graphene, has the potential to increase the abrasion resistance of rubber and thus their lifespan as well. In this research, hybrid styrene‐butadiene rubber‐based (SBR) nanocomposites reinforced with carbon black, silica and various amounts of graphene nanoplatelets are investigated with great emphasis on their combined effects on the mechanical properties of the rubber samples. Sixty‐five phr of precipitated silica can holistically improve the properties of SBR. However, further addition of carbon black and graphene nanoplatelets to silica‐containing samples do not benefit the properties of the samples. Further studies on the compatibilization of silica with carbon‐based reinforcement are necessary. On the other hand, graphene and carbon black constitute an effective hybrid reinforcement system. The tensile strength and elongation at break of SBR are improved by almost 100% with 10 phr of graphene nanoplatelets in combination with 10 phr of carbon black. However, the abrasion resistance of samples was negatively influenced by the addition of graphene nanoplatelets whenever it was added in combination with other fillers. Silica was particularly effective in increasing the abrasion resistance of rubber.
