离子通道尺寸的可控性对离子传输和筛分至关重要。氧化石墨烯（GO）具有平面二维结构和丰富的官能团作为结合位点，液晶材料在外力作用下一般会发生取向变化。因此，可以将这一特性融入到氧化石墨烯中，通过设计符合要求的液晶电池，调节外部力场，控制氧化石墨烯层间的距离，从而控制离子的输运。本文以液晶和氧化石墨烯为原料，通过氢键制备了多层夹心纳米纸，并研究了其受控离子输运行为。在外加电场或磁场的作用下，夹心氧化石墨烯纳米纸层间距离的离子通道可因介观取向的改变而发生调节；因此，当锂离子溶液通过纳米纸时，离子电导率可以被调节。这种纳米纸材料在离子传输、分离系统、离子电池和电容器装置等许多领域显示出前景。图形抽象
ABSTRACT The controllability of ion channel size is critical for ion transport and sieving. Graphene oxide (GO) has a planar two-dimensional structure and a rich functional group as a binding site, and the liquid crystal material generally undergoes an orientation change under the action of an external force field. Therefore, this property can be incorporated into GO, and the distance between the layers of GO can be controlled by designing the liquid crystal cell which meets the requirements and adjusting the external force field, thereby controlling the transport of ions. In this paper, multilayer sandwich nanopapers were fabricated by liquid crystals and GO via hydrogen bonding, and the controlled ion transport behaviour was investigated. In the presence of external electric or magnetic field, ion channels in the interlayer distance of sandwich GO nanopapers can be adjusted due to the changes of mesogen orientation; therefore, ion conductivity can be adjusted when a lithium-ion solution pass through the nanopapers. Such nano-paper materials show promise in many fields such as ion transport, separation systems, ion battery and capacitor devices. Graphical abstract
