A great effort is given to make flexible thermoelectric modules to convert thermal energy to electric energy, recently. A thermoelectric
module is fabricated by connecting several p- and n-type thermoelectric material couples. Although air stable ptype
polymeric thermoelectric materials made progress in performance and stability, n-type polymeric materials are still confronted
with significant challenges for achieving efficient and stable thermoelectric material.
An efficient n-type thermoelectric material was simply produced in this study by mixing the TiS2 with PEDOT:PSSA dispersion
and then ultra-sonicating the mixture in an ice bath. The highest power factor of 1516 = microW m–1 K–2 was achieved
and the highest figure of merit, ZT of 1.14 was estimated at 300 K by assuming 0.4 W m–1 K–1 of the thermal conductivity of
the composite containing 20% of TiS2. To the best of our knowledge, this power factor is the highest among the n-type polymeric
thermoelectric materials reported in the literature.
