“…Furthermore, another significant approach to enhance the PF of PANI-based composites is by hybridizing inorganic nanoparticles which possess intrinsic high σ or S, meanwhile retaining the merits of organic PANI polymers. Various inorganic materials were chosen as the TE enhancing fillers into the PANI matrix, including metal nanoparticles, 71,72 metal sulfides, [73][74][75][76] metal oxides, [77][78][79][80] metal selenides, 37,81 and metal tellurides, 82,83 etc. On one hand, in order to obtain an enhanced σ, Roussel et al blended metallic silver (Ag) particles into PANI matrix.…”

Polyaniline (PANI)-based thermoelectric (TE) materials have attracted great attention for flexible electronic energy harvesting devices because of the advantages of solution processibility, excellent environmental stability and low cost. However, the typical opposite dependence between electrical conductivity and Seebeck coefficient impedes their development, and tremendous efforts have been devoted to increasing their TE

“…The voids in the composites are filled with air and there are two types of interfaces in the composites: the MWNTs/polymer interfaces and the air/composites interface. As reported, the phonons mismatch and poor interfacial bonding between the MWNTs and polymer resulted in severe phonon scattering at the interface so that the thermal conductivities of polymer/MWNT composites are far lower than the theoretical values [9,33]. Yu et al reported that the porous structure could retain the low thermal conductivity of polymer composites, even when loaded with a high content of CNTs.…”

Abstract:In this paper, a solvent vapor-induced phase separation (SVIPS) technique was used to create a porous structure in polyvinylidene fluoride/Multi-walled carbon nanotube (PVDF/MWNTs) composites with the aim of increasing the electrical conductivity through the incorporation of MWNTs while retaining a low thermal conductivity. By using the dimethylformamide/acetone mixture, porous networks could be generated in the PVDF/MWNTs composites upon the rapid volatilization of acetone. The electrical conductivity was gradually enhanced by the addition of MWNTs. At the same time, the thermal conductivity of the PVDF film could be retained at 0.1546 W·m −1 ·K −1 due to the porous structure being even by loaded with a high content of MWNTs (i.e., 15 wt.%). Thus, the Seebeck coefficient, power factor and figure of merit (ZT) were subsequently improved with maximum values of 324.45 µV/K, 1.679 µW·m −1 ·K −2 , and 3.3 × 10 −3 , respectively. The microstructures, thermal properties, and thermoelectric properties of the porous PVDF/MWNTs composites were studied. It was found that the enhancement of thermoelectric properties would be attributed to the oxidation of MWNTs and the porous structure of the composites. The decrease of thermal conductivity and the increase of Seebeck coefficient were induced by the phonon scattering and energy-filtering effect. The proposed method was found to be facile and effective in creating a positive effect on the thermoelectric properties of composites.

Thermoelectric materials allow direct conversion of waste heat energy into electrical energy, thus contributing to solving energy related issues. Polymerbased materials have been considered for use in heat conversion in the temperature range from 20 to 200 °C, within which conventional materials are not efficient enough, whereas polymers due to their good electronic transport properties, easy processability, non-toxicity, flexibility, abundance, and simplicity of adjustment, are considered as promising materials. Due to the large variety of available polymers and the almost unlimited combinations of possible modifications, the field of polymer-based thermoelectrics is very rapidly developing, already reaching efficiency values close to those of inorganic systems. In the current progress report, the most recent advances in the field are discussed. New approaches to improve thermoelectric performance are described, with a focus on revising the mechanisms to improve the thermoelectric properties of the three most investigated polymer matrixes: poly(3,4-ethylenedioxythiophene) polystyrene sulfonat, poly(3hexylthiophene-2,5-diyl), and polyaniline, alongside the three main paths of optimizing properties: incorporation of carbon-based material and inorganic substances, and treatment with chemical agents. The most promising research in the field is highlighted and thoroughly analyzed. The path toward a lab-to-fab transition for thermoelectric polymers is suggested in perspective.
