제목 Fabrication of flexible and printed Sb2Te3 nanoplates/PEDOT:PSS composite thermoelectric film
초록 Thermoelectric(TE) materials are widely studied for applications for waste heat recovery and refrigeration, due to their ability to convert thermal energy directly into electrical energy.[1] Over the past years, inogarnic thermoelectric materials showed high performance TE materials of high figure of merits (ZT=σα2/κ).  Recently,   hybrid composites,  with inorganic and organic materials, are on rise as an appealing option for thermoelectric applications because of low fabrication costs. In this study, we fabricated a hybrid composite of Sb2Te3 nanoplates/ Poly(3,4-ethylenedioxythiophene) Poly(styrenesulfonate) (PEDOT:PSS) with different contents of Sb2Te3. First, we synthesis Sb2Te3 nanoplates via the hydrothermal method. Characterization using SEM and TEM, we observed that the nanoplates were synthesized as single crystal.  Then, we mixed the nanoplates with PEDOT:PSS matrix with various mixing ratios (20,40,60 and 80 weight ratio(wt%) of Sb2Te3) to produce a thin thermoelectric film. We coated the solution on a flexible substrate by screen printing and obtained a uniform film. Finally, we measured electrical and thermoelectric properties of the films. The results of this study highlights the possibility of employing this material for various thermoelectric applications.
