Abstract
En 中文
The introduction of a hierarchy of pores into a conjugated polymer improves its thermoelectric performance. Zhang et al. created irregularly shaped pores in selenium-substituted diketopyrrolopyrrole by adding polystyrene as a phase-separating agent. After removing the polystyrene, the porous structure showed enhanced phonon-like scattering, which lowered its thermal conductivity, was more crystalline, and had improved charge transport. These films had a thermoelectric figure-of-merit of 1.64 at 343 Kelvin. —Phil Szuromi
