Abstract

This letter studies the unexplored phenomenon of the wetting of liq. crystals inside C nanopipes. C nanopipes are similar to C nanotubes but are open ended with straight walls. Using environmental SEM, the authors obsd. liq. crystal menisci inside the nanopipes. Raman spectroscopy was used to confirm the presence of liq. crystals confined in the nanopipes and verify the phys. interaction between the 2 materials. Observations from reflection polarized optical microscopy expts. suggest the use of liq. crystals inside C nanotubes to develop electrooptic switches.
