MXene is a general term for complex atomic layer compounds composed of early transition metals (such as titanium, vanadium) and light elements (carbon or nitrogen), with a layered structure similar to graphene. The surface of the sheets has various polar functional groups, which gives them high dispersibility in hydrophilic materials.
It is expected to be used as electrode materials in lithium-ion batteries, sodium-ion batteries, supercapacitors, electromagnetic shielding materials, separation membranes, and sensor materials.
