Rapid production of 3D porous superstructures for energy storage and infrared stealth

3D porous superstructures hold tremendous potential for energy storage, mass transport, and shielding layers. Achieving superstructures with high conductivity, considerable porosity, and robust foldability, however, still presents a significant challenge. This Preview highlights the rapid fabrication of 3D porous MXene superstructures via a simple acid-base neutralization reaction. The obtained superstructures exhibit remarkable absolute shielding effectiveness and capacitance retention and promising high-temperature infrared camouflage capability. These findings present a comprehensive understanding of 3D porous superstructures and their advantages for various applications. 3D porous superstructures hold tremendous potential for energy storage, mass transport, and shielding layers.

Rapid foaming of dense MXene films induced by acid-base neutralization reactionYin et al.Cell Reports Physical ScienceMay 25, 2023In BriefYin et al. report on an acid-base neutralization reaction to rapidly foam MXene films. The facile foaming reaction results in porous MXene foams that exhibit good foldability, EMI shielding, electrochemical capacitance, and infrared stealth properties, and the strategy can be extended to other 2D materials such as graphene oxide.
