2D Materials 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 led to improvements in the mechanical strength and toughness, electrical conductivity, and shielding from electromagnetic interference.
