영어 초록
Flexible transparent conducting films (TCFs) were fabricated by dip-coating single-wall carbon
nanotubes (SWCNTs) onto a flexible polyethylene terephthalate (PET) film. The amount
of coated SWCNTs was controlled simply by dipping number. Because the performance of
SWCNT-based TCFs is influenced by both electrical conductance and optical transmittance,
we evaluated the film performance by introducing a film property factor using both the number
of interconnected SWCNT bundles at intersection points, and the coverage of SWCNTs on
the PET substrate, in field emission scanning electron microscopic images. The microscopic
film property factor was in an excellent agreement with the macroscopic one determined
from electrical conductance and optical transmittance measurements, especially for a small
number of dippings. Therefore, the most crucial factor governing the performance of the
SWCNT-based TCFs is a SWCNT-network structure with a large number of intersection
points for a minimum amount of deposited SWCNTs.
