제목 Conductive polymer based Polyaniline/tin(II) sulfide nanosheet composites for high-performance hybrid thermoelectrics
초록 Composites of SnS nanosheets with conductive polyaniline (PANI) are fabricated to achieve high-performance hybrid thermoelectric materials. SnS nanosheets with sizes from 200 to 500 nm are prepared from a SnS ingot by applying a Li-intercalation and chemical exfoliation process and are incorporated with conductive PANI. The thermoelectric power factor of the SnS nanosheet/PANI composites is optimized by manipulating the content of SnS nanosheets in the composite, and the changes in the thermoelectric properties are examined and discussed with respect to the carrier transport properties. The maximum power factor of 3.62 μW/m·K2 is obtained with the SnS nanosheet/PANI composite containing 20 wt.% of SnS nanosheets, attributed to the dominance of the improvement in the Seebeck coefficient over the reduction in the electrical conductivity. The incorporation of conductive PANI and SnS nanosheets is a promising strategy for high-performance thermoelectric applications.
