2D transition metal carbides (MXenes) in metal and ceramic matrix composites

Abstract

Two-dimensional transition metal carbides, nitrides, and carbonitrides (known as MXenes) have evolved as competitive materials and fillers for developing composites and hybrids for applications ranging from catalysis, energy storage, selective ion filtration, electromagnetic wave attenuation, and electronic/piezoelectric behavior. MXenes’ incorporation into metal matrix and ceramic matrix composites is a growing field with significant potential due to their impressive mechanical, electrical, and chemical behavior. With about 50 synthesized MXene compositions, the degree of control over their composition and structure paired with their high-temperature stability is unique in the field of 2D materials. As a result, MXenes offer a new avenue for application driven design of functional and structural composites with tailorable mechanical, electrical, and thermochemical properties. In this article, we review recent developments for use of MXenes in metal and ceramic composites and provide an outlook for future research in this field.

Machine-learning-assisted analysis of transition metal dichalcogenide thin-film growth

“…Our results suggest that the ML-assisted RHEED analysis could be developed into an automatic validation method for investigating ultrathin 2D materials films, and it is complementary to other surface analysis tools [ 7 , 38 , 39 ]. Furthermore, this method can be applied to analyze the thin-film growth of other 2D materials, such as 2D chalcogenides, 2D MXenes, 2D oxides, and hexagonal boron nitrides [ 40 – 43 ].…”

Hydrogen deblending future and emerging technology watch

“…Transition metal carbides, nitrides and carbonitrides (MXene) are 2D materials that can be incorporated into metal and ceramic matrices to offer favourable properties. 49 MXene membranes have very similar structure to GO membranes, with hydroxyl, fluoro, and oxide groups creating interlayer pathways resulting in the high H2 permeability and selectivity. 29 The use of high toxicity hydrogen fluoride (HF) in MXenes manufacture and their susceptibility to oxidation appear to be just two of numerous issues that must be overcome to implement them effectively.…”

Construction of Wheat Bran Biomass Porous Aerogel by Starch Pasting for Fabrication of Phase Change Composites with High Latent Heat Storage and Temperature Regulation

“…7,8 Nonetheless, some shortcomings of PCMs make them impossible to use alone 9,10 and an effective solution to prevent their leakage is to package them with support materials. 11 PCMs can be well confined in the porous matrices by capillary forces and intermolecular forces, 12 which mainly including polymers, 13 oxides, 14 carbons, 15 biomass, 16 ceramics, 17 etc. Usually, porous biomass materials are nontoxic and biodegradable, which greatly satisfy the requirement of green energy when using them as support materials for PCMs.…”
