Abstract
2D material hydrogels have recently sparked tremendous interest owing to their potential in diverse applications. However, research on the emerging 2D MXene hydrogels is still in its infancy. Herein, we show a universal 4D printing technology for manufacturing MXene hydrogels with customizable geometries, which suits a family of MXenes such as Nb

, respectively, surpassing most state-of-the-art devices. This work brings new insights into MXene hydrogel manufacturing and expands the range of their potential applications.
2D MXene hydrogels are promising for diverse applications. Here, the authors report a universal 4D printing technology to manufacture MXene hydrogels with customizable geometry, high conductivity, and efficient pseudocapacitive energy storage ability.
