Research progress in electromagnetic absorption by MXene/conductive polymers composites

MXene是一种新型的具有类石墨烯结构的二维纳米片层材料,其出色的导电性和丰富的官能团使其在吸波应用中显示巨大潜力,但过高的电导率导致阻抗匹配差,影响电磁吸收。导电聚合物(CPs)因低密度、耐腐蚀、电导率可调等特点在吸波领域应用广泛,但其低吸波强度特征形成了需与其他材料复合的需求。MXene/CPs复合材料可实现良好的阻抗匹配、介电损耗协同,提升吸波能力、增加带宽。从CPs与MXene的吸波原理及应用综述了MXene/导电聚合物复合吸波介质的研究进展,对电磁吸收材料的发展趋势进行展望。

MXene is a novel two-dimensional nanosheet material with a graphene-like structure.Its excellent conductivity and rich functional groups make it highly promising for absorbing applications.However,its excessive conductivity leads to poor impedance matching and affects electromagnetic absorption.Conductive polymers(CPs)are widely used in the field of microwave absorption due to their low density,corrosion resistance,and adjustable conductivity,but their low absorption intensity characteristics create a demand for compositing with other materials.MXene/CPs composite materials can achieve good impedance matching,synergistic dielectric loss,enhancing absorption capacity and increasing bandwidth.This article reviewed the research progress of MXene/conductive polymer composite absorbing media based on the absorption principles and applications of CPs and MXene,and looked forward to the development trend of electromagnetic absorbing materials.
