Abstract

Unique nanoscale transport properties of carbon nanotubes (CNTs) have inspired researchers for over a decade, initially with their analogies to various biological pores and later with the potential impact on water purification. Water can permeate through a nanometer-wide pipe of the CNT interior at rates far exceeding those predicted by Hagen-Poiseuille formulation and measured in nano conduits of different material, attributed to nano confinement, hydrophobicity, and smooth potential energy landscape. Also, chemical addition to the nanotube ends was found effective in electrostatic exclusion of ions without much loss of water permeability, suggesting the emergence of CNT membranes for desalination and purification of water resources. This article introduces Carbon Nanotube Nanofluidics by capturing important findings and progresses made in the early developments of the area.
