MXene Nanocomposites: Multifunctional Nanocomposites with High Strength and Capacitance Using 2D MXene and 1D Nanocellulose (Adv. Mater. 41/2019)

In article number 1902977, Liangqi Ouyang, Mahiar M. Hamedi, and co-workers report the fabrication of freestanding and multifunctional nanocomposite films of 2D Ti3C2Tx MXene and 1D cellulose nanofibrils (CNFs) with a high mechanical strength of 341 MPa and high conductivity of 295 S cm−1. These films, despite their high mechanical robustness, deliver a high capacitance of 298 F g−1, which places them among the best multifunctional supercapacitor electrode materials reported to date. The stable and patternable hybrid dispersion of 2D Ti3C2Tx MXene and 1D CNFs is also used to fabricate micro-supercapacitor electrodes and printed electronics with a variety of shapes.
