<![CDATA[This study aims to enhance the mechanical and thermal properties of polymer blends (HDPE and PP) by incorporating nanofillers, including carbon nanotubes (CNTs), graphene oxide (GO), and silica nanoparticles (SiO₂). The effects of nanofiller concentrations (1%, 2%, and 3% by weight) on tensile, impact, and flexural strengths, and thermal stability were investigated. The results showed that adding 2% CNTs increased tensile strength by 50% compared to the unmodified blend. Impact and flexural strengths also improved significantly with the addition of CNTs, while the improvements were less pronounced with GO and SiO₂. Thermal stability was enhanced by all nanofillers, with the CNT and GO composites showing a 25% increase in decomposition temperature compared to the unmodified blend. X-ray diffraction analysis revealed that nanofillers increased the crystallinity of the blends, thereby improving strength and stability. These findings suggest that CNTs, GO, and SiO₂ significantly enhance the mechanical and thermal properties of polymer blends, making them suitable for applications in industries such as automotive, aerospace, and electronics.]]>
