제목 Exploring Wholly Doped Conjugated Polymers for Optimization of Electrical Conductivity and Related Thermoelectric Properties
초록 Molecular doping is a common strategy to improve the electrical conductivity of Conjugated Polymers(CPs). Herein, we suggest a novel doping method, ‘hybrid doping‘, that can fully extract maximum of employed CPs by wholly doping crstalline and amorphous regions. We strategically hybridized mixture blending and sequential processes and made use of each process’s advantages. Using the hybrid doping, we achieved of P3HT up to 80.39 S cm-1 Furthermore, hybrid doping effectively worked for less crystalline CP, PIDF-BT, by increasing its up to 639.04 S/cm which indicates the general applicability of hybrid doping. Remarkably conductive CP films prepared by hybrid doping complemented decreased Seebeck coefficient and featured optimized thermoelectric effect, power factor up to 76.05 µWm-1K-2. Based on these results, we believe that this simple but very effective hybrid doping method can be a versatile process for optimizing both electrical and thermoelectrical properties of various CPs.
