The hollow inside of a carbon nanotube (CNT) is attracted as a nanoscale channel for fluid transfer and material storage. However, previous studies related to those applications are focused on CNT with liquid inside, whereas the studies during liquid filling process is limited. In the present study, we stuck the CNT tip into liquid surface under vacuum condition and this experiment was observed by scanning transmission electron microscopy (STEM) to visualize the meniscus behavior. There found stop motion of meniscus and it is explained by capillary action with intermolecular force between CNT inner wall and liquid. In addition, voids inside the liquid infused into CNT were found by STEM, Rayleigh-Plateau instability would be the reason of this generation mechanism.
