Abstract
Transmission electron microscopy (TEM) experiments are performed on carbon nanotubes filled with a multiphase aqueous fluid. It is shown through high resolution TEM that the dense aqueous fluid wet the inner surface of the carbon nanotube, possibly due to the presence of oxygen-based groups, which modify the carbon surface such that it becomes hydrophilic. Electron energy loss spectroscopy (EELS) analysis confirms the presence of oxygen inside the fluid-filled nanotubes, as well as on the inner and outer surfaces of the nanotube walls. Fluid experiments involving controlled liquid evaporation and condensation, as driven by external heating, demonstrate that liquid transport in nanochannels of less than 100 nm in diameter is achievable. The present results offer promise for the development and functional performance of future micro- and nanofluidic devices.
