Abstract

In this paper, the carbon nanotube was well dispersed into the poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) solution with a best concentration of 4 mg/ml. The prepared sol was spun on poly(ether sulfone) (PES) substrates, showing sheet resistance as low as 19.8 Ω/sq and the high average transmittance over 90%. The change in optical and electrical properties due to poly(ether sulfone) (PES) substrate was investigated to understand the failure mechanisms. For realizing the bending effect on electrical performance, the pre-deposited ZnO buffer was introduced to improve the deterioration during the repeated bending test. The composite polymer enhanced the electrical conductivity with less detrimental effect on the optical transparency, which suggests the potential transparent conductive films for use in developing optical and electrical device.
