In this work, a transparent conductive films were fabricated using poly(3,4-ethylene dioxythiopene) (PEDOT)/carboxyl methyl cellulose (CMC) and carbon nanotubes (CNTs) by solution casting method. CNTs were acid-treated to improve the dispersity in the polymer resin and O2 plasma treated poly(ethylene terephthalate) (PET) was used as a flexible substrate. Transparency and conductivity of the PEDOT/CMC/CNTs films at room temperature was evaluated by different contents of CNTs. As a result, the highly dispersed CNTs in PEDOT/CMC were observed by SEM and TEM images. PEDOT/CMC/CNTs films showed transparency over 80% by UV-Vis-NIR spectroscopy and low sheet resistance less than 200 Ω/sq at 0.02 wt% CNT content. In addition, this film showed the flexibility and would not breakdown upon banding and folding in contrast with ITO. |
