Abstract
Conjugated polymers have attracted attention as promising materials for thermoelectric (TE) devices due to their lightweight and flexible nature. their thermoelectric performance is mainly evaluated by the power factor (PF = σS²), where S and σ are the Seebeck coefficient and electrical conductivity, respectively.
In this study, two conjugated polymers with relatively high S and σ, respectively, were blended to improve thermoelectric performance.
To gain a deeper understanding of thermoelectric properties in polymer blend systems, the electrical, optical, morphological, and nanostructural characteristics of polymer blend films were systematically investigated at various blend ratios.
As a result, at an optimized blend condition, enhanced σ and optimized S led to an approximately 100% improvement in PF compared to the single-polymer. This finding indicates that our blend systems present an effective strategic pathway enabling synergistic optimization of σ and S.
