Synthesis, Properties, and Applications of Nanocomposite Materials Based on Bacterial Cellulose and MXene

Abstract

MXene exhibits impressive characteristics, including flexibility, mechanical robustness, the capacity to cleanse liquids like water through MXene membranes, water-attracting nature, and effectiveness against bacteria. Additionally, bacterial cellulose (BC) exhibits remarkable qualities, including mechanical strength, water absorption, porosity, and biodegradability. The central hypothesis posits that the incorporation of both MXene and bacterial cellulose into the material will result in a remarkable synthesis of the attributes inherent to MXene and BC. In layered MXene/BC coatings, the presence of BC serves to separate the MXene layers and enhance the material’s integrity through hydrogen bond interactions. This interaction contributes to achieving a high mechanical strength of this film. Introducing cellulose into one layer of multilayer MXene can increase the interlayer space and more efficient use of MXene. Composite materials utilizing MXene and BC have gained significant traction in sensor electronics due to the heightened sensitivity exhibited by these sensors compared to usual ones. Hydrogel wound healing bandages are also fabricated using composite materials based on MXene/BC. It is worth mentioning that MXene/BC composites are used to store energy in supercapacitors. And finally, MXene/BC-based composites have demonstrated high electromagnetic interference (EMI) shielding efficiency.

Synthesis and Optical Properties Investigation of Nanosized Two-Dimensional (Fe1−xSrx Cr2O4)/MXene Nanocomposite

“…The advantage of making Fe1-xSrx Cr2O4/MXene nanocomposite with the Mxene instead of graphene because MXenes are becoming increasingly popular because they integrate good electric conduction with crucial processability and morphological benefits. 44 In the present work, Fe 1−x Sr x Cr 2 O 4 /MXene, x = 0.2, 0.4, 0.6, 0.8 nanocomposites are prepared using the Co-precipitation method. The band gap of the synthesized nanocomposite is observed to reduce to 2.06 eV, while for MXene our measured value of the band gap is 3.33 eV.…”
