Effect of mixing solvent and the oxidant on the polymerization of 3,4-ethylenedioxythiophene (EDOT) |
| 초록 |
The effect of oxidant (FeCl3 and ferric tosylate) and solvent on vapor phase polymerization of poly(3,4-ethylenedioxythiophene) (PEDOT) thin films on APS-coated SiO2 surfaces were studied. As increase the concentration of oxidant the PEDOT film thickness were also subsequently increased. In case of ethanol solvent while the concentration of the FeCl3 was increased the porous site and size also increased. All iron ought to be removed from the film by heavy washing by methanol but iron was detected by Auger Electron Spectroscopy (AES) measured. Using tetrahydrofuran (THF) and ethanol (50:50) mixing solvent, the PEDOT film conductivity reach (~600 S/cm) compared to only using the ethanol solvent conductivity was ~450 S/cm. Iron was absent in the film up to 7wt.% of feCl3 solution confirmed by Energy Dispersive X-ray Spectroscopy (EDS) measurement, in the 50:50 (ethanol : THF) solvent. Fourier transform-infrared spectroscopy (FT-IR) data also revealed that the main characteristic peak of PEDOT which is responsible for the quinodal like structure was more intense than the only using the Ethanol solvent. . The ferric tosylate oxidant added pyridine in ethanol solvent also studied on the polymerization of EDOT. At optimized condition ~720 S/cm conductivity was achieved. |
