“…The highest obtained power factor was 4.94 μWm −1 K −2 for the ACR/PANI sample, making this a potential coating for powering waste energy recycling. This value is very close to systems reported in the literature, such as PANI/GR pellets (5.6 μWm −1 K −2 ) 4 and PANI/CNT composite pellets (~5.0 μWm −1 K −2 ) 57 . It is also higher than other reported systems such as PANI/Graphite pellets (~1.5 μWm −1 K −2 ) 58 and PANI/PbTe pellets (~0.7 μWm −1 K −2 ) 59 .…”

Thermoelectric (TE) materials have attracted attention for offering a green option for power generation, due to their ability to convert thermal energy into electricity. In recent years, a promising way to achieve efficiency in TE properties has been proposed based on composites of conjugated polymers, such as polyaniline (PANI), and carbon nanomaterials such as graphene (GR). Since polyaniline and GR composites are promising fillers for organic thermoelectric materials (OTE), we expanded their investigations for a ternary system (TS), providing materials with multiple functionalities, and high performance. In this research work, a TS based on an acrylic matrix (ACR), GR, and PANI was successfully prepared through the combination of in situ polymerization of aniline in contact with GR and mechanical mixture of the resulting hybrid with an ACR. Structural and morphological characterization confirmed that GR affected PANI morphology and crystallinity. The band gap determination by Tauc's relation indicated the occurrence of π‐π interaction between the chains and an increase of the electrical conductivity of the composites allowed to infer a synergistic effect. The measured Seebeck coefficient reached a maximum value of −17.02 μVK−1 and the highest power factor obtained was 4.94 μWm−1 K−2 for the ACR/PANI sample, indicating a material with promising thermoelectric properties.
