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.
MXene具有令人印象深刻的特性，包括柔韧性、机械坚固性、通过MXene膜净化诸如水等液体的能力、吸水性以及抗菌效果。此外，细菌纤维素（BC）具有显著的品质，包括机械强度、吸水性、孔隙率和生物降解性。核心假设是将MXene和细菌纤维素都融入材料中会导致MXene和BC固有属性的显著综合。在层状MXene/BC涂层中，BC的存在有助于分离MXene层，并通过氢键相互作用增强材料的完整性。这种相互作用有助于使该薄膜获得高机械强度。将纤维素引入多层MXene的一层中可以增加层间空间并更有效地利用MXene。与普通传感器相比，利用MXene和BC的复合材料由于这些传感器表现出更高的灵敏度，在传感器电子领域已获得显著关注。水凝胶伤口愈合绷带也是使用基于MXene/BC的复合材料制造的。值得一提的是，MXene/BC复合材料用于超级电容器中储存能量。最后，基于MXene/BC的复合材料已展示出高电磁干扰（EMI）屏蔽效率。
