The
wetting behavior of an ionic liquid (IL) on individual carbon
nanotubes (CNTs) was experimentally investigated using <i>in
situ</i> electron microscopy. The tip of a single CNT was brought
into contact with the surface of the IL using a nanomanipulator. The
formation of a meniscus was observed immediately at the contact point.
A thin layer of IL also formed simultaneously across the entire CNT
surface. The force because of wetting was measured using the Wilhelmy
method. After correcting the macroscale classical equations by considering
an “apparent” diameter that corresponds well with the
thickness of the IL layer on individual CNTs, the experimental data
indicated that the wettability of single CNTs with diameters of over
10 nm was subjected to classical laws at the macroscale.
