Constructions and applications of MXene-based porous films

Abstract

Abstract MXene-based films (MBFs) have a graphic structure composed of a horizontal arrangement of MXene thin tablets and/or layer interval parts. It usually has high electrode density, but high-rate charge transfer is limited, and ions are transmitted to oxidize the activity site. To overcome these problems, it is necessary to convert the plane configuration of the MXene membrane into an interactive structure with an open and porous architecture. In this paper, the first discovered and most widely studied Ti3C2Tx MXene materials are used as an example to introduce the unique construction methods of MXene-based porous film structures, structure-effect relationships, and the applications: supercapacitor, terahertz electromagnetic shielding, and flexible sensing, which show significantly improved performance.
