“…The flakes exhibited good transparency within darker areas indicating their 2D structure, which is also consistent with the MXene-devoted literature. 45,46 The high-resolution TEM (HRTEM) (Figure 2d) further revealed a few-layered (FL) structure of the edge-viewed 2D MXene nanoflakes. In addition, the SADP (Figure 2e) confirmed the minor presence of layered Ti 3 C 2 T x (denoted by blue rings) with the coexistence of TiO 2 (denoted by red rings).…”

Polypropylene (PP) is a thermoplastic polymer widely used as a medical textile in healthcare applications due to its low cost and superior performance. However, it does not show antibacterial properties leading to the possibility of pathogen transmission. Herein, we have developed an antibacterial medical fabric by facile self-assembly of delaminated two-dimensional (2D) Ti 3 C 2 T x MXene flakes bristling on the surface of PP fibers. The increasing amount of MXene in the coating solution from 1 up to 32 mg/mL allowed for edge-on assembly of MXene flakes on the PP surface and tracking the evolution of the band gap for a restacked structure. Characterization of the PP/Ti 3 C 2 T x nanocomposite has proven that it exhibited highly effective antibacterial, robust coating, and chemically/thermally stable properties. The in vitro microbiological studies against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus have shown that PP/Ti 3 C 2 T x reduced the bacterial viability up to 100%, as driven by synergistic membrane stress mediated by physical contact and light-induced reactive oxygen species (ROS) generation. Moreover, the use of L-ascorbic acid for MXene stabilization allowed for achieving excellent thermal stability of the PP/Ti 3 C 2 T x nanocomposite upon accelerated thermal aging. Collectively, this work provides a facile surface engineering strategy for designing medical fabrics with outstanding functional performances. By demonstrating the exceptional performance of the stabilized MXene in a self-assembly nanocomposite structure, we are opening the door for MXenes to be applied in other biomedical fields.

“…In addition, TiO 2 and MnO 2 have also been hybridized with MXene, forming TiO 2 / MXene and MnO 2 /MXene heterostructure electrodes. 207,208 In general, the Li + ion storage performances of MXene and MXene/TMO heterostructure electrodes are affected by many factors, including the structure, functional groups, interlayer spacing, conductivity, and components. Therefore, constructing MXene/TMO heterostructures with excellent large interlayer spacing, large termination groups, and high electronic conductivity could significantly facilitate the kinetics and Li + storage performance.…”

extraordinary optical, mechanical, and electronic properties. [1][2][3] MXenes (singular; MXene; pronounced "maxenes") are a class of 2D inorganic compounds that are composed of few-atom-thick layers of transition metal nitrides, carbides, or carbonitriles. [4] The first MXene, Ti 3 C 2 T x , was reported in 2011 by Naguib et al. without any prior prediction for the stability of such 2D materials. [5] MXenes (MXs) have a general chemical formula of M n+1 X n T x (n = 1-3) and are generally synthesized by the delamination of quaternary and tertiary 3D compounds called MAX phases. [6][7][8] In the chemical formula, M signifies a transition metal (e.g., Ti, Sc, Zr, Nb, etc.), X is C and/ or N, and T x is the oxygen, fluorine, or hydroxyl terminals consequent from the synthetic precursors (Figure 1). [9][10][11][12][13][14][15][16] MXenes can also be synthesized from other layered precursors such as Mo 2 Ga 2 C and Zr 3 Al 3 C 5 . After the establishment Ti 3 C 2 T x as of the first MXene, numerous MXenes have been synthesized and predicted theoretically. [17][18][19][20][21] Typically, MXenes are synthesized using a top-down approach that accounts for selective etching of A-layer from 3D crystalline-layered nitrides and carbides (MAX phases; Figure 2). [22] In MAX phases, M n+1 X n layers are held together by an atomic layer of an A-group transition element, usually group 13 or 16 group elements, principally Ga, Si, P, As, and Al. [23] The structures of three possible MAX phases are shown in Figure 2a. MAX phases themselves can be manufactured by the sintering of
