摘要:

MXenes作为一类新兴的二维材料, 因具有独特的亲水性、 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性能而成为研究热点, 广泛应用在电磁屏蔽、 电化学储能、 生物医药、 分离、 传感器和海水淡化等领域. 虽然MXenes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其实际应用. 近年来, 通过对MXenes进行界面调控以解决其固有缺陷, 并在此基础上对MXenes进行针对性的结构设计以提升界面稳定性, 其性能得到了进一步提升. 本文对MXenes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MXenes的结构和性质及MXenes在复合材料中的界面调控手段, 对MXenes复合材料的结构设计进行了阐述, 并对MXenes复合材料的发展前景进行了展望.

Abstract:

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