Summary: | In this paper, the fabrication of highly conductive and transparent films of single-walled carbon nanotubes (SWCNTs) and poly(3,4-ethylenedioxythiophene) (PEDOT) on top of polyethylene terephthalate film (PET) substrates is demonstrated using electropolymerization without sacrificing transparency. A sheet resistance of 250 Ω sq
−1
is achieved with a transparency of 93% at a 550 nm wavelength. The enhancement in the conductivity was attributed to the ability to bridge the gaps between the individual carbon nanotubes with the help of PEDOT, which increases the number of electric tube–tube junction contacts within the SWCNT network.
Poly(3,4-ethylenedioxythiophene) is electropolymerized on a single-walled carbon nanotube film to reduce sheet resistance without causing loss in transparency. |
