Carbon nanotubes (CNTs) are well known for their remarkable electrical, optical, and mechanical properties; however, in recent years, there has been a growing interest in mass-transport properties through the inner core of CNTs or the interstice in a vertically oriented CNT array. This chapter discusses state-of-the-art approaches in the fabrication of macroscopic membranes from such nanoscale materials. The usefulness of this exciting material for various applications, in the light of their extremely fast mass-transport characteristics, chemical tuneability, and stimuli-responsive behavior, is elaborated. In addition, we discuss the potential of these membranes in applications such as functional nanofluidic components in microfluidic platforms, electrochemical membrane reactors, and desalination of seawater. Finally, major challenges and directions of future research of this emerging area are also discussed.
