MXene based nanocomposite films

Abstract Since the first report in 2011, two‐dimensional transition metal carbide/nitride MXenes have aroused widespread attention owing to the particular structure and physiochemical properties. In the last few years, MXene‐based nanocomposite films have been widely investigated, showing promising applications in many fields. However, poor mechanical properties and thermal/electrical conductivities of MXene‐based nanocomposite films still limited their practical applications. Herein, we summarize the fabrication approach of MXene‐based nanocomposite films and discuss the mechanical properties and other applications, including electromagnetic interference shielding, thermal conductivity, and supercapacitors. Then, several vital factors for fabricating high performance MXene based nanocomposite films have been refined. To further fabricate high performance MXene‐based nanocomposite films, some effective sequential bridging strategies are also discussed. Lastly, a conclusion of the challenges and opportunities of MXene‐based nanocomposite films is provided to facilitate their development and application for various purposes in the future of scientific research.
