在这里，我们提出了一种廉价的简易湿化学自由的方法转移的化学气相沉积的多壁碳纳米管的柔性透明聚合物基板在一个单一的步骤的过程。通过控制纳米管的长度，我们展示了对转移薄膜的电导率和光学透明度的精确控制。高达140%的单轴应变仅引起样品电导率的轻微降低，从而在可拉伸电子产品中开辟了许多应用。纳米管对齐为诸如极化选择性电极和柔性超级电容器基板的应用提供了增强的功能。由所报道的干转移MWCNT制造的超级电容器的电容为17 F/g，相应的循环伏安图显示出对纳米管长度的明显依赖性。
Herein we present an inexpensive facile wet-chemistry-free approach to the transfer of chemical vapour-deposited multiwalled carbon nanotubes to flexible transparent polymer substrates in a single-step process. By controlling the nanotube length, we demonstrate accurate control over the electrical conductivity and optical transparency of the transferred thin films. Uniaxial strains of up to 140% induced only minor reductions in sample conductivity, opening up a number of applications in stretchable electronics. Nanotube alignment offers enhanced functionality for applications such as polarisation selective electrodes and flexible supercapacitor substrates. A capacitance of 17 F/g was determined for supercapacitors fabricated from the reported dry-transferred MWCNTs with the corresponding cyclic voltagrams showing a clear dependence on nanotube length.
