Abstract

This study investigates the influence of TiO₂ nanoparticles on the thermal behavior of polystyrene (PS) and high-density polyethylene (HDPE) nanocomposites. PS/TiO₂ and HDPE/TiO₂ films were prepared using a solution mixing technique followed by hot pressing, and their thermal properties were examined through differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Incorporation of TiO₂ enhanced the thermal stability of both polymer systems. In HDPE/TiO₂, low nanoparticle concentrations acted as nucleating agents, slightly increasing the melting onset associated with the semicrystalline nature of HDPE. For PS/TiO₂, the melting temperature (Tm) and glass transition temperature (Tg) increased with nanoparticle loading, indicating restricted chain mobility due to strong interfacial interactions. A reduction in enthalpy of melting (ΔH) and crystallinity (Xc) in both systems confirmed that TiO₂ disrupted polymer crystallinity. TGA results further revealed increased decomposition temperatures for the nanocomposites compared to neat polymers. These findings demonstrate that TiO₂ nanoparticles effectively enhance the thermal resistance and stability of PS and HDPE, making them promising candidates for advanced thermal-demanding applications.
