Control of The Electrostatic Interaction Between PEDOT and PSS to Improve Thermoelectric Output |
| 초록 |
We modified the electrostatic interaction of poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS) using alkylsulfonate anions with different lengths of alkyl chain; this systematic control not solely increased electrical conductivity but the Seebeck coefficient of PEDOT:PSS films. The intervention of added anions increased molecular ordering of PEDOT domain as tearing down existing tight-bounded state, and caused the conformational change of PEDOT:PSS in solution and film state. Furthermore, different lengths of alkyl chains on added anions controlled the doping level of PEDOT backbone by different degrees of weakening the electrostatic interaction between PEDOT and PSS; this increased the Seebeck coefficient. These optimizations for thermoelectric properties overcame the established inverse-relation between thermoelectric properties; this reached a remarkable power factor (~1055.87 μW/mK2) in PEDOT:PSS films. |
