Comparison of thermoelectric properties of a p-doped planar CPDT based polymer with various doping methods |
| 초록 |
We synthesized a p-type thermoelectric polymer based on cyclopentadithiophene and benzothiadiazole, poly[(4,4’-(bis(hexyldecylsulfanyl)methylene)cyclopenta[2,1-b:3,4-b’]dithiophene)-alt (benzo[c][1,2,5]thiadiazole)] (PCPDTSBT) and investigated its thermoelectric properties by varying doping methods. Sequentially doped films; immersed into the dopant solution and overcoating the dopant solution on top of the neat polymer film, show higher electrical conductivity (＞100 S cm-1) than solution co-processed film (~40 S cm-1). We measured different electrical, morphological and thermoelectric behaviors by changing doping methods. Polaron generation by doping was confirmed as a main charge carrier by UV/Vis absorbance and electron spin resonance spectroscopy. The electrical conductivity was studied by a 4 points probe method. The detailed film morphology of the pristine and doped polymer films was investigated by atomic force microscopy and grazing incidence wide angle X-ray scattering. |
