A three-dimensional (3D) cellular MXene (Ti3C2Tx) film is fabricated through the filtration assembly of MXene microgels and a subsequent freeze-casting process. Fully exposed MXene nanosheets create a high-ion-accessible surface area, and the highly interconnected MXene networks facilitate ion transport, which enable the 3D cellular MXene film to acquire a high-rate energy storage. Moreover, the continuous conductive porous structure endows such film with a superior absolute electromagnetic interference shielding effectiveness (127083 dB cm2 g–1). This work provides a facile strategy for building a 3D macroporous MXene film and opens up the opportunities to explore the other uses of MXene.

轻巧的三维蜂窝MXene膜,可实现出色的能量存储和电磁干扰屏蔽
通过MXene微凝胶的过滤组件和随后的冷冻浇铸工艺,制造了三维(3D)多孔MXene(Ti 3 C 2 T x)薄膜。完全暴露的MXene纳米片可创建高离子可及的表面积,高度互连的MXene网络可促进离子传输,这使3D蜂窝MXene膜能够获得高速率的能量存储。此外,连续的导电多孔结构使这种薄膜具有出色的绝对电磁干扰屏蔽效果(127083 dB cm 2 g –1)。这项工作为构建3D大孔MXene膜提供了一种简便的策略,并为探索MXene的其他用途提供了机会。
