Abstract

MXene has excellent electrical conductivity, abundant surface functional groups and wonderful film-forming properties, but the lamellar layers are prone to self-stacking during film formation, which will reduce the loss of electromagnetic waves, hinder ion transmission, and limit the effective load of other functional materials. The construction of the porous structure can effectively solve the self-stacking problem of MXene sheets. This article reviews the research progress of MXene porous films for electromagnetic interference (EMI) shielding, lithium/sodium ion batteries, pseudocapacitors, and biomedical science applications. It focuses on the preparation methods of MXene porous films, and discusses the pore-forming mechanisms of the porous structure formed by different preparation methods and the internal relationship between the "microstructure-macro performance" of the MXene porous films, points out the key scientific and technical bottlenecks that need to be solved urgently in the preparation and application of the MXene porous films. It is hoped to provide certain guidance for the design, preparation, optimization, industrial application and development of MXene porous films.

MXene具有優(yōu)異的導(dǎo)電性、豐富的表面官能團(tuán)以及極佳的成膜性,但成膜時片層極易發(fā)生自堆疊,會降低其對電磁波的損耗、阻礙離子傳輸,還會限制其它功能材料的有效負(fù)載。多孔結(jié)構(gòu)的構(gòu)建可以有效解決MXene片層的自堆疊問題。本文綜述了電磁干擾(EMI)屏蔽、鋰/鈉離子電池、贗電容器和生物醫(yī)用領(lǐng)域用MXene多孔膜的研究進(jìn)展,著重介紹了MXene多孔膜的制備方法,探討了不同制備方法形成多孔結(jié)構(gòu)的成孔機(jī)理以及MXene多孔膜微觀結(jié)構(gòu)-宏觀性能的內(nèi)在關(guān)系,指出了MXene多孔膜在制備以及應(yīng)用過程中亟待解決的關(guān)鍵科學(xué)和技術(shù)瓶頸問題,希冀能為MXene多孔膜的設(shè)計制備優(yōu)化、工業(yè)化應(yīng)用及發(fā)展提供一定的指導(dǎo)。
