A critical review of MXene/nanocellulose composite films

MXene/nanocellulose composite films have received special attention by combining the characteristics of emerging two-dimensional (2D) inorganic nanosheets and one-dimensional (1D) organic nanofibers. In recent years, the research progress of MXene/nanocellulose composite films has been rapid, with good performance and application prospects. Herein, we criticize the developments of MXene/nanocellulose composite films. Firstly, the synthesis methods of MXene/nanocellulose composite films are reviewed. Secondly, their various applica-tions are summarized, including electromagnetic interference shielding, sensor, energy, environmental field. The interaction mechanism between 2D inorganic MXene and 1D organic nanocellulose has received special atten-tion. In addition, the current challenges and development directions potential for MXene/nanocellulose films were also proposed. It is expected that there will be rapid development of MXene/nanocellulose composite films.
