“…MXenes have mostly been employed to reinforce polymeric materials; however, they can be deployed to strengthen the metallic/ceramic materials. [85,159] Several reinforcing agents, such as CNTs and graphene, have already been tested in metals; however, agglomeration and poor wettability have been a big problematic challenge in metal matrix composites.

“…[161] Fei et al [162] produced MXene-reinforced ceramic matrix nanocomposites where 2.0 wt% Ti 3 C 2 T x incorporated into alumina exhibited an improved fracture toughness, bending strength, and hardness by ≈300%, ≈150%, and ≈300%, respectively. In another attempt, Wozniak et al [159] fabricated a MXene-reinforced silicon carbide (SiC) matrix nanocomposite by a powder metallurgy route wherein the fracture toughness and the hardness values were improved by ≈55% and ≈18%, respectively when the SiC matrix was filled by 1.5 wt% Ti 2 C; the mentioned improvements are probably due the two strengthening mechanisms, i.e., crack deflection and crack bridging effects, being decelerating crack growth and propagation. Hu et al [161] dealt with the mechanical properties and the frictional resistance of aluminum Ti 3 C 2 T x MXene filled nanocomposites fabricated by pressureless sintering being followed by an extrusion process; the tensile strength of 148 MPa (≈65% improvement), the hardness of 520 MPa (≈90% improvement) and the friction coefficient of 0.2 (≈200% reduction) were observed in the sample reinforced by only 3 wt% Ti 3 C 2 T x .…”

MXenes are recently discovered 2D nanomaterial with superior mechanical, thermal, and tribological properties, being commonly employed in a wide variety of critical research areas, ranging from cancer therapy to energy and environmental applications. Due to their special properties, such as mechanoceramic nature with excellent mechanical performance, thermal stability and rich surface properties, MXenes have tremendous potential as advanced composite structures, especially those based on polymers due to a great affinity between macromolecules and the terminating groups of 2D MXenes. MXenes have been extensively explored in metal matrix nanocomposites as well as in solid‐ or liquid‐based lubrication systems owing to the 2D structure and antifriction characteristics. The purpose of the this paper is to provide a comprehensive insight into the material, mechanical, and tribological properties of the MXene nanolayers with discussions on the recent advancements attained from MXene‐reinforced nanocomposites starting with the synthesis, fabrication techniques, intricacies of the underlying physics and mechanisms, and finally focusing on the progress in computational studies. This analysis of MXene‐based composites will stimulate an emerging field with innumerable opportunities and ample potentials to produce newfangled materials and structures with targeted properties.

2D transition metal carbides and nitrides (MXenes) are electrochemically active materials capable of exhibiting pseudocapacitance. Multilayer MXenes are similar to graphite, but with larger interlayer spacing and surface functionalities which allow them to readily disperse in water and undergo a range of reactions without compromising their electrical conductivity. The large interlayer spacing enables MXenes to readily intercalate large ions, and form composites with materials such as graphene, metal oxides, transition metal dichalcogenides and silicon, with which they make electrodes able to deliver exceptional capacities at high power rates over thousands of cycles. Research into MXenes for energy storage has grown exponentially since 2011, and it is now necessary, especially for readers new to the field, to review progress made in more specific areas. This critical review will therefore analyse the progress made in developing MXene‐based batteries, focusing solely on anodes developed for metal‐ion batteries such as Li‐ion, Na‐ion and K‐ion.

“…They were first discovered in 2011 during studies on the application of MAX phases in supercapacitors by Naguib, Barsoum, and Gogotsi from Drexel University, USA [10]. This new class of nanomaterials has so far demonstrated significant potential in many applications, such as energy storage [11], ceramic matrix composites [12–14], and macromolecules’ adsorption [15]. Other studies also revealed possibilities of their usage as biocides [16–18], in nanomedicine [19], or environmental remediation [20].…”

BackgroundThe biological activity of MXenes has been studied for several years because of their potential biomedical applications; however, investigations have so far been limited to 2D titanium carbides. Although monolayered Ti2NTx MXene has been expected to have biological activity, experimental studies revealed significant difficulties due to obstacles to its synthesis, its low stability and its susceptibility to oxidation and decomposition.ResultsIn this paper, we report our theoretical calculations showing the higher likelihood of forming multilayered Ti2NTx structures during the preparation process in comparison to single-layered structures. As a result of our experimental work, we successfully synthesized multilayered Ti2NTx MXene that was suitable for biological studies by the etching of the Ti2AlN MAX phase and further delamination. The biocompatibility of Ti2NTx MXene was evaluated in vitro towards human skin malignant melanoma cells, human immortalized keratinocytes, human breast cancer cells, and normal human mammary epithelial cells. Additionally, the potential mode of action of 2D Ti2NTx was investigated using reactive oxygen tests as well as SEM observations. Our results indicated that multilayered 2D sheets of Ti2NTx showed higher toxicity towards cancerous cell lines in comparison to normal ones. The decrease in cell viabilities was dose-dependent. The generation of reactive oxygen species as well as the internalization of the 2D sheets play a decisive role in the mechanisms of toxicity.ConclusionsWe have shown that 2D Ti2NTx in the form of multilayered nanoflakes exhibits fair stability and can be used for in vitro studies. These results show promise for its future applications in biotechnology and nanomedicine.
