“…In fact, the word of "Graphene" was proposed by Boehm in 1986 and defined by the International Union of Pure and Applied Chemistry in 1997. [3] Graphene, a one atom thick layer of carbon with a honeycomb lattice in the form of sp 2 hybridization (Figure 2a), has attracted significant interest due to its fascinating properties, such as high carrier mobility (200 000 cm 2 V −1 s −1 ) at room temperature, ballistic electronic transport (mean free path over 0.4 µm), high thermal conductivity (5300 W m −1 K −1 ), high light transmittance (97.7%), high Young's modulus (130 GPa), and its highly specific surface area (2630 m 2 g −1 ). [4][5][6][7] It indicates broad application prospects in the fields of flexible wearable devices, photoelectric detectors, high-efficiency radiator, energy storage, and so on.…”

Numerous studies conducted on the layered graphene family—including the monolayer, bilayer, trilayer, few‐layer, and multilayer—draw plenty of attention to stacking modes and twist angles, which are extensively explored for its controlled growth, properties, and applications. This review provides a comprehensive overview of current challenges and opportunities for the chemical vapor deposition (CVD) growth, characterization, and electrical properties of graphene depending on the layer number and twist angles. Various state‐of‐the‐art innovations using the CVD method, which incorporates graphene synthesis through the control of metal substrates, layer numbers, and twist angles, are presented. The underlying growth mechanisms are discussed in terms of the interactions among graphene substrates/layers and its dynamic process. The characterization methods for determining the layer number and twist angle of graphene layers are summarized. Furthermore, the electrical properties and applications of graphene, particularly magic‐angle twist bilayer graphene, are briefly introduced. Finally, outlooks and perspectives for the engineering of CVD graphene layers are discussed.

“…Simulation calculation analysis not only contributes to the improvement and optimization of the CVD reactor design but also explains the reaction mechanisms, including those of low-dimensional nanomaterials. Controllable equipment provides a theoretical basis [ 177 ], and CFD simulations can be divided into two main categories: chemical simulations of CVD, and the specific structural designs and its numerical simulations of the CVD reactor.…”

Carbon nano-materials have been widely used in many fields due to their electron transport, mechanics, and gas adsorption properties. This paper introduces the structure and properties of carbon nano-materials the preparation of carbon nano-materials by chemical vapor deposition method (CVD)—which is one of the most common preparation methods—and reaction simulation. A major factor affecting the material structure is its preparation link. Different preparation methods or different conditions will have a great impact on the structure and properties of the material (mechanical properties, electrical properties, magnetism, etc.). The main influencing factors (precursor, substrate, and catalyst) of carbon nano-materials prepared by CVD are summarized. Through simulation, the reaction can be optimized and the growth mode of substances can be controlled. Currently, numerical simulations of the CVD process can be utilized in two ways: changing the CVD reactor structure and observing CVD chemical reactions. Therefore, the development and research status of computational fluid dynamics (CFD) for CVD are summarized, as is the potential of combining experimental studies and numerical simulations to achieve and optimize controllable carbon nano-materials growth.

Exfoliated graphite (ExG) embedded in a polymeric matrix represents an accessible, cost-effective, and sustainable method for generating nanosized graphite-based polymer composites with multifunctional properties. This review article analyzes diverse methods currently used to exfoliate graphite into graphite nanoplatelets, few-layer graphene, and polymer-assisted graphene. It also explores engineered methods for small-scale pilot production of polymer nanocomposites. It highlights the chemistry involved during the graphite intercalation and exfoliation process, particularly emphasizing the interfacial interactions related to steric repulsion forces, van der Waals forces, hydrogen bonds, π-π stacking, and covalent bonds. These interactions promote the dispersion and stabilization of the graphite derivative structures in polymeric matrices. Finally, it compares the enhanced properties of nanocomposites, such as increased thermal and electrical conductivity and electromagnetic interference (EMI) shielding applications, with those of neat polymer materials.
