摘要: MXene作为一类新兴的二维材料,因其具有独特的亲水性、优异的力学性能、丰富的表面官能团、高导电率、光热以及光电效应等优势而成为研究热点,广泛应用在电磁屏蔽、电化学储能、生物医药、分离、传感器、海水淡化等领域。虽然MXene具有这些优异的性能,但是其存在的与疏水性高分子相容性差,带负电的官能团阻碍电解质运输及易氧化等问题限制了实际应用的需求。近年来,通过对MXene进行界面调控,旨在解决其固有的缺陷,并在此基础上,对MXene进行针对性的结构设计,提升界面稳定性,使其性能得到进一步提升。本文对MXene复合材料发展过程中在界面调控和结构设计方面的研究进展进行总结,并重点介绍了MXene的结构和性质、MXene在复合材料中的界面调控手段,对MXene复合结构形式进行了阐述,并对MXene复合材料的发展前景进行了展望。

Abstract: As an emerging type of two-dimensional material, MXene has become a research focus because of its unique advantages including hydrophilicity, excellent mechanical properties, abundant surface functional groups, high conductivity, photothermal and photoelectric effects. As a result, it has been widely used in electromagnetic shielding, electrochemical energy storage, biomedicine, separation, sensor and seawater desalination. Although MXene has these excellent properties, its drawbacks such as poor compatibility with hydrophobic polymers, the impediment of electrolyte transport by negative charged functional groups and the ease of oxidation, all limit its practical application. Recently, efforts have been made by interface modification of MXene to solve its inherent defects. Subsequently, targeted structural design of MXene is carried out to improve the interface stability and further enhance its performance. In this paper, the research progress of interface modification and structure design of MXene composites is summarized, in which the structure and properties of MXene, the interface modification methods of MXene and the structure strategies of MXene composite are discussed followed by a brief prospect of MXene composite materials.
