MXene/CNTs复合材料的制备及应用进展

Progress in the preparations and applications of MXene/CNTs composites

MXene和碳纳米管作为两大低维材料,已被广泛应用于诸多领域。然而MXene材料因其特有的片层结构及丰富的表面官能团,在实际研究中仍与理论值存在较大差距。从MXene材料的特征及制备方法出发,结合现有碳纳米管的研究基础综合讨论了MXene/碳纳米管复合材料从制备到应用的研究进展。MXene材料和碳纳米管进行复合具有更优异的性能,再加上MXene更好的亲水性和良好的分散稳定性,使MXene/CNTs复合材料的制备更加多样化,能够在应变传感、电磁屏蔽、催化、高介电材料、电池和超级电容器电极材料方面具有很大的应用前景。

MXene and carbon nanotubes,as two prominent low-dimensional materials,have been widely used in many fields.However,MXene materials are still far from the theoretical values in practical studies because of their unique lamellar structure and abundant surface functional groups.This paper discussed the research progress of MXene/CNTs composites from preparations to applications based on the characteristics and preparation methods of MXene materials,combined with the existing carbon nanotubes researches.The composite of MXene materials and carbon nanotubes offered superior performance,along with MXene's better hydrophilicity and good dispersion stability,which made the preparation of MXene/CNTs composites more diversified and could have great prospects for applications in strain sensing,electromagnetic shielding,catalysis,high dielectric materials,battery and supercapacitor electrode materials.
