摘要
MXenes是一种电阻很小且导电能力很强的二维晶体材料,在电池、传感器、电磁屏蔽、医疗方面都具有很大的应用潜能。为了研发制备更多的MXenes,国内外学者开展了许多制备工艺研究和应用的探索。针对MXenes独特的层次结构、化学组成、物理性能,综述了MXenes制备工艺的研究进展,对比分析了每种制备方法的优点和需要进一步解决的问题。指出:在未来的研究中,氟化氢刻蚀法的研究重点是如何提高MXenes的电容性和插层问题;原位刻蚀法对刻蚀时间、温度、环境的要求较高,需要攻克的难点是这些因素的影响机理以及相应的改善措施;电化学腐蚀法制备的MXenes中没有—F官能团,但是研究的重点将是对沉淀物的分离和净化;熔融盐法制备MXenes正是起步阶段,需要进一步的开发和研究。
MXenes is a two-dimensional crystal material with low resistance and strong conductivity.It has great application potential in batteries,sensors,electromagnetic shielding,and medical treatment.In order to develop and prepare more Mxenes,scholars at home and abroad have carried out a lot of research on preparation process and exploration of application.Aiming at the unique hierarchical structure,chemical composition and physical properties of MXenes,the research progress on the preparation process of MXenes was reviewed,and the advantages of each preparation method and the problems that need to be further solved were compared and analyzed.It was pointed out that in future research,the research focus of hydrogen fluoride etching method would be how to improve the capacitance and intercalation of MXenes;the in-situ etching method would have higher requirements on etching time,temperature and environment,and the difficulties to be overcome would be the influence mechanism of these factors and the corresponding improvement measures;there would be no—F functional group in MXenes prepared by electrochemical corrosion method,but the focus of research would be on the separation and purification of precipitates;the preparation of MXenes by molten salt method was just in its infancy,and further research was needed development and research.
