Polyaniline/graphitic carbon nitride/reduced graphene oxide ternary nanocomposite film for flexible thermoelectric application Manoj Singh, Amish Kumar Gautam, Mohd Faraz, Neeraj Khare Nanotechnology, 2024 The present study outlines the preparation of a ternary nanocomposite film comprising of polyaniline doped with camphor sulfonic acid (PANI), reduced graphene oxide (rGO), and graphitic carbon nitride (g-C3N4), and delves into its thermoelectric performance. PANI is known to possess high electrical conductivity (σ) and poor thermal conductivity (κ). However, its potential for thermoelectric applications is constrained by the low value of the Seebeck coefficient (S). The incorporation of g-C3N4 in PANI has been demonstrated to result in an improvement of the Seebeck coefficient. Furthermore, the addition of rGO to the PANI/g-C3N4 sample counteracts the decrease in electrical conductivity. The PANI/g-C3N4/rGO ternary nanocomposite film exhibits an enhanced Seebeck coefficient of ∼2.2 times when compared to the PANI sample. The Seebeck coefficient of the PANI/g-C3N4/rGO nanocomposite is enhanced by the energy filtering effect that occurs at the interfaces between g-C3N4/PANI and PANI/rGO. The π–π interaction between the PANI chains and rGO is responsible for the increased electrical conductivity resulting from the well-ordered polymer chain arrangement on the g-C3N4 and rGO surfaces. The ternary nanocomposite sample demonstrated a synergistic improvement in both electrical conductivity and Seebeck coefficient, resulting in a remarkable ∼4.6-fold increment in power factor and an ∼4.3-fold enhancement in the figure of merit (zT), as compared to the pristine PANI film.
Flexible, Freestanding Ternary Nanocomposite Thick Film of Polyaniline/WS2/CNTs for Efficient Thermoelectric Application Manoj Singh, Amish Kumar Gautam, Mohd Faraz, Neeraj Khare ACS Applied Energy Materials, 2024 Conducting polymers are promising for near-room-temperature, wearable thermoelectric applications due to their flexibility, inherently low thermal conductivities, and tunable electrical conductivities. This work reports the fabrication of a flexible nanocomposite thick film consisting of conducting polymer, polyaniline (PANI), WS 2 nanosheets, and carbon nanotubes (CNTs) and investigates its thermoelectric properties. The incorporation of WS 2 nanosheets results in an ∼3 times enhancement in the Seebeck coefficient because of the high Seebeck coefficient of WS 2 nanosheets and the energy filtering effect at the PANI–WS 2 interface. The incorporation of CNTs acts as a conducting filler in the PANI/WS 2 matrix, which helps in improving the mobility of charge carriers and enhances the electrical conductivity. Hence, the simultaneous incorporation of WS 2 nanosheets and CNTs synergistically increases the Seebeck coefficient and the electrical conductivity in the nanocomposite thick films, which results in an ∼13 times enhancement in the power factor and an ∼10 times enhancement in the figure of merit (zT) at room temperature in comparison to pristine PANI film. The study suggests that the simultaneous incorporation of WS 2 nanosheets and CNTs in PANI is a promising strategy to improve the thermoelectric properties of PANI-based materials.
