“…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

“…Wide bandgap materials in small quantities can significantly improve the TE performance of the polymer matrixes. Sarkar and co‐workers [ 98 ] studied the effect of addition of NiO as a wide bandgap semiconductor to the aniline monomers solution during polymerization, resulting in a composite with concentrations of filler from 0.25% to 1.25%. In‐situ polymerized composites showed that NiO can serve as the bridge to interconnect polymer chains, preventing the crystal growth, which disturbs the transport of charge carriers.…”

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.

“…1,12 However, PANI is brittle and insoluble in organic solvents, which results in poor processability and limits its application. Although researchers have focused on developing a suitable ller to modify PANI properties for use in devices such as corrosion inhibiter, 13 supercapacitors, 14,15 thermoelectric generators, 16,17 and gas/vapor sensors, 18 the degradation in mechanical performances of PANI-based composites due to the aggregation of particles and PANI brittleness remains a problem. 19 Cellulose derivatives are ideal materials for reinforcing 20 composites because of their renewability, sustainability, and biodegradability.…”
