The self-assembly of nanoscale materials at the liquid-liquid interface allows for fabrication of three-dimensionally structured liquids with nearly arbitrary geometries and tailored electronic, optical, and magnetic properties. Two-dimensional (2D) materials are highly anisotropic, with thicknesses on the order of a nanometer and lateral dimensions upward of hundreds of nanometers to micrometers. Controlling the assembly of these materials has direct implications for their properties and performance. We here describe the interfacial assembly and jamming of TiCT MXene nanosheets at the oil-water interface. Planar, as well as complex, programmed three-dimensional all-liquid objects are realized. Our approach presents potential for the creation of all-liquid 3D-printed devices for possible applications in all-liquid electrochemical and energy storage devices and electrically active, all-liquid fluidics that exploits the versatile structure, functionality, and reconfigurability of liquids.
纳米级材料在液-液界面的自组装能够制造出具有几乎任意几何形状以及定制化电子、光学和磁性能的三维结构化液体。二维（2D）材料具有高度各向异性，厚度在纳米量级，横向尺寸从数百纳米到微米级以上。控制这些材料的组装对其性质和性能有直接影响。我们在此描述了TiCT MXene纳米片在油水界面的界面组装和堵塞情况。实现了平面以及复杂的、可编程的三维全液体物体。我们的方法为制造全液体3D打印设备提供了潜力，这些设备可能应用于全液体电化学和能量存储设备以及利用液体的多功能结构、功能和可重构性的电活性全液体流体ics中。
