SnSe/PEDOT:PSS composites are fabricated and show high thermoelectric performance. Introduction of SnSe nanosheets contribute to the enhancement of Seebeck coefﬁcient. Solvent treatment greatly enhances electrical conductivity of the composite. ar ti c l e i nf o ab stra ct Article history: Organic polymer based thermoelectric ﬁlms consisting of poly(3,4-ethylenedioxythiophene):poly(styre Received 10 January 2016 nesulfonate) (PEDOT:PSS) with inorganic tin selenide (SnSe) nanosheets were fabricated. Two- Received in revised form 24 March 2016 dimensional SnSe nanosheets were prepared by Li intercalation and subsequent exfoliation process from Accepted 25 March 2016 the synthesized bulk ingot. Different amounts of SnSe nanosheets were evenly distributed in the PEDOT: Available online 2 April 2016 PSS matrix, producing various SnSe/PEDOT:PSS composites. The thermal conductivity of the composites was found to be insensitive to the addition of SnSe nanosheets.
