在目前的工作中，我们已经开发出一种简单而有效的方法来制备超长垂直排列的碳纳米管（SLVA-CNT）和环氧树脂复合膜，我们已经证明，各种液体，包括水，己烷，和十二烷，可以有效地通过SLVA-CNT膜。这些结果通过分子动力学模拟得到证实。虽然机械致密化用于进一步增强通过SLVA-CNT膜的流动传输，但我们在本研究中开发了一种磁性纳米颗粒切换系统，通过简单地施加交流电压来打开和关闭通过纳米管膜的流动。在这项研究中开发的方法应该有一个显着的意义，先进的智能系统的各种智能膜的发展。
In the present work, we have developed a simple but effective method to prepare superlong vertically aligned carbon nanotubes (SLVA-CNT) and epoxy composite membranes, and we have demonstrated that various liquids, including water, hexane, and dodecane, can effectively pass through the SLVA-CNT membranes. These results were confirmed by molecular dynamics simulations, While the mechanical densification was used to further enhance the flow transport through the SLVA-CNT membranes, we developed in this study a magnetic-nanoparticle switching system to turn on and off the flow through the nanotube membrane by simply applying an alternating voltage. The methodologies developed in this study should have a significant implication to the development of various smart membranes for advanced intelligent systems.
