“…To overcome these issues graphene based metal matrices composites prepared via by ball milling and hot-press sintering can produced homogenous mixture [217]. In these composites main problem is very low bonding between graphene and metallic matrices and limitation of full densification for bulk matrix composites, this hardship is depend on its preparation method, most useful method is powder metallurgy [218].…”

Two-dimensional (2D) graphene and its outstanding properties such as, enormous conductivities, mechanical strength, optical and electrical properties brought it one of the most studied materials for the production of energy using renewable resources. The composites of graphene with the same morphological materials such as layered transition metal oxides will be the most aspiring combination to boost their conducting, optoelectronic and mechanical properties. Furthermore, the transition metal chalcogenides materials attracted significant attention due to their atomically thin layers and enormous optical, conducting and electrical properties. The layered materials offer mostly atomically thin 2D plane to the charge carrier with superior conducting properties. The thickness at atomic level, band gap, spin orbit coupling electronic and optoelectronics properties of transition metal dichalcogenides makes them one of the promising entities in energy harvesting technologies. The review suggests some strategies to improve the transition metals-composites stability conducting properties to be tailored in various applications.

Through molecular dynamics simulations of tensile tests, the role that vacancies and Stone-Wales defects play in the mechanical properties of sandwich-like heterostructures, composed by graphene and two symmetric copper layers at nanoscale, is studied. The dependence on the armchair and zigzag chiralities of the graphene layer is also investigated. During elastic deformation, defects negatively affect the mechanical response. However, defective systems can show an improvement of the plastic properties. Vacancies have a stronger impact compared to Stone-Wales defects. Elasticity, toughness, and ductility are enhanced along the zigzag chirality, while stiffness is improved along the armchair direction. The Poisson’s ratio was calculated for all graphene-copper heterostructures. At a critical strain it becomes negative along the thickness direction, preserving the auxetic property at higher strains. In general, the behavior is governed by the graphene response. Our findings can be useful to understand the strengthening mechanism induced by this two-dimensional material in metals like copper and for the design of similar systems.

“…enhanced hardness and crack resistivities, yet its application as functional high-temperature materials is still debatable [23]. Graphene is also known to strengthen metallic composites, with 0.1 wt% graphene increasing the ultimate tensile strength of copper by 1.8 times [24]. Graphene's strength, hardness, and self-lubricating properties allow it to be used as secondary reinforcement in the synthesis of light weight self-lubricating composites for aerospace and automobile applications [25].…”

Graphene is an advanced carbon functional material with inherent unique properties that make it suitable for a wide range of applications. It can be synthesized through either the top–down approach involving delamination of graphitic materials or the bottom–up approach involving graphene assembly from smaller building units. Common top–down approaches are exfoliation and reduction while bottom–up approaches include chemical vapour deposition, epitaxial growth, and pyrolysis. A range of materials have been successfully used as precursors in various synthesis methods to derive graphene. This review analyses and discusses the suitability of conventional, plant- and animal-derived, chemical, and fossil precursors for graphene synthesis. Together with its associated technical feasibility and economic and environmental impacts, the quality of resultant graphene is critically assessed and discussed. After evaluating the parameters mentioned above, the most appropriate synthesis method for each precursor is identified. While graphite is currently the most common precursor for graphene synthesis, several other precursors have the potential to synthesize graphene of comparable, if not better, quality and yield. Thus, this review provides an overview and insights into identifying the potential of various carbon precursors for large-scale and commercial production of fit-for-purpose graphene for specific applications.
