“…It was shown that, in terms of their morphometric parameters, the obtained 2D graphene structures belong to FLG [7]. To date, it has been shown that the obtained FLG is promising in polymer materials science [9], as a basis for radionuclides sorbent [10]. The ability to obtain FLG in product volume sufficient for real application and the shown promise of their use in a wide range of practical applications determined the choice as an object of this research FLG synthesized using the SHS process.…”

A quantitative method is proposed to determine of Stone-Wales defects for carbon nanostructures with sp2 hybridization of carbon atoms. The technique is based on the diene synthesis reaction (Diels-Alder reaction). The proposed method was used to determine Stone-Wales defects in the few-layer graphene (FLG) nanostructures synthesized by the self-propagating high-temperature synthesis (SHS) process, in reduced graphene oxide (rGO) synthesized based on the method of Hammers and in the single-walled carbon nanotubes (SWCNT) TUBAL trademark, Russia. Our research has shown that the structure of FLG is free of Stone-Wales defects, while the surface concentration of Stone-Wales defects in TUBAL carbon nanotubes is 1.1×10-5 mol/m2 and 3.6×10-5 mol/m2 for rGO.

“…In 2020, thermophysical properties and the strength of NBR nanocomposites using high‐quality graphene nanoplatelets (GnPs) were studied. [ 57 ] GnPs were synthesized by the self‐propagating high‐temperature synthesis (SHS) method. An increase in tensile strength, thermal conductivity, and anti‐wear was achieved due to the homogeneity of the GnPs in the polymer matrix.…”

Polymer composite materials fabricated from acrylonitrile-derived polymers (such as polyacrylonitrile, nitrile butadiene rubber, styrene-acrylonitrile, acrylonitrile butadiene styrene) with suitable fillers have found tremendous applications due to their highly desirable properties. Graphene, a versatile 2D carbon nanomaterial, with extraordinary properties has been adopted as an effective filler component of a wide range of acrylonitrile-based polymer composites. The modified and functionalized graphene-based nanomaterials were incorporated into the acrylonitrile-based polymer matrix to enhance their various properties. In contrast to conventional 1D carbon nanoparticles, the incorporation of this graphene into the polymer matrix resulted excellent improvement in mechanical, electrical, rheological, and thermal, as well as frictional properties. This has offered advances in diverse applications such as sensors, flexible electronics, Li-S battery, damping, structural, microwave shielding, aircraft, spacecraft, automobile, and so forth. Particularly, the excellent EMI (Electromagnetic interference) shielding ability of these acrylonitrilebased polymer/graphene composites has been explored widely in microelectronics. This review focuses on the recent progress and new strategies in the development of different acrylonitrile-based polymer/graphene nanocomposites.

This study investigated the crack propagation behavior of the graphene-reinforced synthetic rubber matrix nanocomposite materials. Graphene-filled rubber conductive nanocomposites developed within the scope of this study were obtained in two stages using mechanical mixers. The relationship between crack propagation and electrical resistance change was investigated using single-edge notched specimens in a tensile tester. Digital image correlation (DIC) technique was used to observe the crack resistance function depending on the local strain distribution. The results from the tests were evaluated to define the relationship between the crack length, the amount of conductive filler, and the change in electrical resistance. The sharp edges of the graphene nanoplatelets negatively affected the fracture resistance of the samples. In addition, it was observed that even at low strain values, gaps were formed in the areas close to the crack tip. The three-dimensional transmission network formed by graphene nanoplatelets dispersed in the matrix improved the electrical conductivity properties of the nanocomposites, so the relationship between crack propagation and electrical resistance change was determined.
