The inherent amphiphilic characteristics of these BCPs enable efficient dispersion of carbon nanotubes (CNTs) in both N-methyl-2-pyrrolidone (NMP) and N,N-dimethylformamide (DMF). These solvents prove instrumental in the fabrication of BCP/CNT thin films, yielding both p-type and n-type nanocomposites. Through optimization of processing conditions, the resultant nanohybrids exhibit tremendous enhancement of thermoelectric properties, with figure of merit (zT) reaching 9.10 × 10−3 and 8.78 × 10−3 at 303 K for p-type and n-type materials, respectively. Molecular Dynamics (MD) simulations confirm the effective interfacial adhesion between the sugar-based BCPs and CNTs. Detailed structural and spectroscopic analyses elucidate the correlation between solvent selection and thermoelectric performance. These findings highlight the potential of this new class of sugar-based BCP/CNT nanocomposites as efficient materials for thermoelectric applications, offering insights into the role of solvent-mediated interactions in optimizing nanocomposite functionality for energy harvesting technologies.falseCarbon nanotubeCompositeSugar-based polymersThermoelectricThermoelectric generatorjournal article10.1016/j.cej.2025.1686122-s2.0-105017008840
