“…The conducting polymer has a low thermal conductivity, which is about 1-3 orders of magnitude lower than those of inorganic materials [8][9][10][11]. Organic TE materials including polyaniline, polyacetylene, polythiophene, and polypyrrole have been intensively evaluated, and the past years have also witnessed their remarkable developments [12][13][14][15]. However, it is found that the zT values of organic TE materials are still too low to be satisfactory, which imposes a great challenge for conducting polymers to be used as TE materials.…”

A significant enhancement in the thermoelectric performance was observed for three-dimensional conducting aerogels, which were obtained from poly(3,4-ethylenedioxythiophene) : poly(4-styrenesulfonic) (PEDOT:PSS) and multiwalled carbon nanotubes (MWCNTs) suspensions by adding different concentrations of metallic silver (Ag). It was found that the electrical conductivity and Seebeck coefficient could be simultaneously increased with the unique structure. Moreover, the conducting aerogels have an ultralow thermal conductivity (0.06 W m −1 K −1 ) and a large Brunauer-Emmett-Teller surface area (228 m 2 g −1 ). The highest figure of merit (zT) value in this study was 7.56×10 −3 at room temperature upon the addition of 33.32 wt.% Ag. Although the zT value was too low, our work may provide new insights into the design and development of the thermoelectric material for applications. Further investigation with PEDOT:PSS aerogels will be continued to get an economical, lightweight, and efficient polymer thermoelectric material.

This study presents the modification of multi‐walled carbon nanotube (MWCNT) with poly(3‐hexylthiophene) (P3HT) and polypyrrole (PPy) through the fast, versatile, and environmentally friendly process of radiofrequency (RF)‐rotating plasma polymerization. Morphological characterization of composites was performed using scanning electron microscopy (SEM) and showed that the P3HT and PPy conducting polymers coated the MWCNT surface. The surface properties of the MWCNT composites were determined using Fourier transform infrared spectroscopy (FTIR), X‐ray photoelectron spectroscopy (XPS), and SEM analysis. MWCNT composites were used as cathodes in dye‐sensitized solar cells (DSSCs). The short circuit current densities of P3HT/MWCNT‐ and PPy/MWCNT‐based DSSCs were found to be 5.61 and 4.19 mA/cm2, respectively. POLYM.

“…This indicates that polymer thermoelectric materials are sufficiently competitive, despite their efficiency being less than that of inorganic or semiconductor materials. For polyaniline [4], the values of electrical conductivity r = 10 S/cm and Seebeck coefficient S = 13 lV/K were obtained, and S = 5 lV/K and r = 21.5 S/cm were attained in polypyrrole films [5]. Also, S = 9 lV/K and r = 80 S/cm have been reported for PEDOT:PSS films with dimethyl sulfoxide (DMSO) treated [6].…”
