我们提出了一种合理而通用的方法，利用液体的拉链效应将管子拉在一起，制备出高密度堆积和排列的单壁碳纳米管(SWNT)材料。这种块状碳纳米管材料保留了单个单壁碳纳米管的固有性质，如高表面积弹性和导电性。通过控制制造过程，可以制造各种形状和结构的固体。这种致密的单壁碳纳米管材料在许多应用中都是有利的，在这里我们展示了它作为柔性加热器和紧凑型储能设备的超级电容器电极的用途。
We present a rational and general method to fabricate a high-densely packed and aligned single-walled carbon-nanotube (SWNT) material by using the zipping effect of liquids to draw tubes together. This bulk carbon-nanotube material retains the intrinsic properties of individual SWNTs, such as high surface area flexibility and electrical conductivity. By controlling the fabrication process, it is possible to fabricate a wide range of solids in numerous shapes and structures. This dense SWNT material is advantageous for numerous applications, and here we demonstrate its use as flexible heaters as well as supercapacitor electrodes for compact energy-storage devices.
