| 제목 | Enhanced Thermoelectric Properties of PEDOT:PSS Thin Films via Spin-coating Method |
| 초록 | Thermoelectric performance, the dimensionless figure of merit (ZT=σS2T/κ) and power factor (PF=σS2) were determined by Seebeck coefficient (S), electrical conductivity (σ), and thermal conductivity (κ). For organic thermoelectric materials, an effective approach of enhancement their thermoelectric properties is to increase Seebeck coefficient and electrical conductivity because of organic materials have inherently low κ. A dispersion poly(3,4-ethylenedioxylthiophene):poly(styrenesulfonate) (PEDOT:PSS) was spin-coated on a glass substrate and then dried at 130℃ for 15 min. After PEDOT:PSS thin films were cooled, organic polar solvents (DMAc, DMF, DMSO, and NMP) were spin-coated on the surface of PEDOT:PSS thin films. To characterize PEDOT:PSS thin films, analytical methods were used such as electrical conductivity, Seebeck coefficient, sheet resistance, Thin films thickness, UV-vis-NIR, raman, XPS, and AFM. |
