3D-printing customized MXene architectures

MXenes are a promising class of 2D materials with unique intrinsic physical and chemical properties, including excellent conductivity, hydrophilicity and high density when compared to graphene. 3D-printed architectures composed of MXenes are particularly attractive for energy storage applications such as rechargeable lithium- and sodium-ion batteries, lithium-sulfur batteries and supercapacitors. Researchers now have demonstrated for the first time the possibility to print three-dimensional freestanding MXene objects.
