摘要
二维材料由于其大的比表面积、高度各向异性、大纵横比等独特性质而被人们广泛研究。由二维材料组装形成的层状薄膜的层间可作为离子选择性传输通道,利用这种特性能够实现可控的离子筛分及能量转换;另外,离子在通道中的传输行为还受到二维材料结构和表面化学的影响。以几种代表性的二维材料为例,阐述了二维纳流体通道的组装、结构、离子传输性质及其调控策略等研究现状,重点对二维纳流体通道在能量储存及转换和离子筛分领域的应用研究做了详细介绍,并对二维纳流体通道在实际应用过程中所面临的关键科学问题进行了提炼和总结,指出了目前限制二维纳流体通道应用的症结所在,同时提出了相应的解决策略。最后,对二维纳流体通道在实际应用中的发展前景进行了展望。
Two-dimensional(2 D)materials have been widely studied due to their unique characteristics including large specific surface area,highly anisotropy and large aspect ratio.The interlayer spacings of lamellar membranes assembled by twodimensional materials can be used as the nanochannels for the ion selective transport,it can realize controllable ion sieving and energy storage and conversion.In addition,the transport behavior of ions inside the channels depends on the structures and surface chemistry of the 2 D building blocks.Taking several typical 2 D materials for examples,this review elaborated the research progress including assembly methods,structures,ion transport properties and the alternation strategies of these 2 D nanofluidic channels,and further focused on their applied research in the fields of energy storage and conversion and ion sieving.Furthermore,the critical scientific issues of the 2 D nanofluidic channels in real application were refined and concluded.The factors that limited the real application of the two-dimensional nanofluidic channels were pointed out,and corresponding strategies were also provided.Finally,the future development of the 2 D nanofluidic channels in practical applications were prospected.
