- PEDOT/SWCNT composite films were prepared via a vapor phase polymerization method.
- The thermoelectric properties of the composite films were measured.
- The thermoelectric properties of the composite films are enhanced compared with pristine PEDOT.
- The enhancement mechanism of the PEDOT/SWCNT films was proposed.
The poly(3,4-ethylenedioxythiophene)/single walled carbon nanotube (PEDOT/SWCNT) composite films with various SWCNT contents (0-50 wt.%) have been prepared by a vapor phase polymerization technique for the first time. The Seebeck coefficients of the composite films increase with the SWCNT contents. The maximum power factor is 37.8 μW mKâ2 for a composite film with 35 wt% SWCNT, which is 1.7 times as high as that of the film without SWCNTs. The composite film with 35 wt% SWCNT has then been treated with a 0.04 wt% NaBH4/DMSO solution and the power factor increases to 44.1 μW mKâ2 after the treatment. The PEDOT chains are more orderly arranged and with decreased doping level by forming composites with SWCNT and may be de-doped further after further treated with NaBH4/DMSO. Therefore, the Seebeck coefficient of the composite film has been further enhanced.
