Carbon-based hybrid nanocomposites are considered as promising candidate materials for thermoelectric applications due to their high electrical conductivity, tunable charge transport characteristics, and structural flexibility. In this study, a facile preparation route was proposed to prepare single-walled carbon nanotube (SWNT)/copper phthalocyanine (CuPc) hybrid structures as thermoelectric materials. As an efficient alternative to the conventional ball-milling method, which requires long processing times and high mechanical energy, a rapid and practical synthesis approach based on an ultrasonic treatment was performed. The SWNTs and CuPc powders were integrated via short-duration ultrasonication in DI water, and the resulting hybrid architectures were processed through vacuum filtration and film coating steps. The structural, chemical, and morphological properties of the as-prepared hybrids were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and field-emission scanning electron microscopy (FE-SEM), respectively. Thermoelectric properties were determined at room temperature by measuring the Seebeck coefficient and electrical conductivity, and the power factor values were calculated accordingly. The results revealed that the ultrasonically produced composites exhibited a competitive power factor as compared to their counterparts prepared via conventional mechanical milling. The findings demonstrate that the proposed facile approach emerges as a viable and cost-effective strategy for the fabrication of SWNT/CuPc thermoelectric hybrids.
