Carbon Nanotubes‐Based Nanofluidic Devices: Fabrication, Property and Application

With the rapid development of nanofluidics, more and more unexpected behaviors and bizarre properties have been discovered, which brings more possibility to solve the water and energy problem. Carbon nanotubes (CNTs) with nanoscale diameter and ultrasmooth hydrophobic surface provide strong confinement and unusual water‐carbon couple which lead to many exotic properties, such as flow enhancement, strong ion exclusion, ultrafast proton transport and phase transition. This article reviews the recent progresses of CNT‐based nanofluidic devices in fabrication, property, and applications. Moreover, challenges and opportunities of the CNT‐based nanofluidic devices are discussed.
