The demand for materials with enhanced thermal management capabilities is increasing, particularly in applications related to thermal comfort such as energy-efficient buildings, textiles, and electronic devices. This study investigates the thermal conductivity of titanium dioxide (TiO₂) and carbon nanotube (CNT) nanocomposites through numerical simulation. TiO₂ nanoparticles were synthesized via a green synthesis route using plant extracts, offering a sustainable and eco-friendly approach. Commercially obtained multi-walled CNTs were incorporated into the TiO₂ matrix at varying concentrations (0.9-0.01 wt%) to form nanocomposites. The effect of CNT loading on the effective thermal conductivity was analyzed using computational modeling techniques. The simulation results demonstrate a significant change in thermal conductivity with increasing CNT concentration, attributed to the low intrinsic thermal conductivity of CNTs and their synergistic interaction with the TiO₂ matrix. The findings suggest that TiO₂-CNT nanocomposites hold strong potential for use in thermal comfort applications where improved heat dissipation and thermal regulation are required.
