Abstract

Densification via bridging layers MXenes are a family of layered two-dimensional metal carbides and nitrides with interesting properties that can be lost if voids are formed during synthesis. By using a sequential combination of hydrogen and covalent bonding agents, Wan et al . were able to densify the layered structure and remove voids. This procedure leads to improvements in the mechanical strength and toughness, electrical conductivity, and shielding from electromagnetic interference. —MSL
