Abstract

This study explores the enhancement of the mechanical and thermal properties of polymer blends (high-density polyethylene and polypropylene) by incorporating nanofillers such as carbon nanotubes, graphene oxide, and silica nanoparticles. The effects of varying nanofiller concentrations (1%, 2%, and 3% by weight) on tensile, impact, and flexural strengths, as well as thermal stability using thermogravimetric analysis (TGA), were investigated. The results showed that the addition of carbon nanotubes provided the most significant improvement, with a 50% increase in tensile strength at a 2% concentration. Graphene oxide and silica nanoparticles also improved mechanical properties, though to a lesser extent. The thermal stability was enhanced by all fillers, with carbon nanotube and graphene oxide composites exhibiting higher decomposition temperatures. X-ray diffraction analysis indicated that the inclusion of nanofillers increased the crystallinity of the polymer blends, contributing to the overall material strengthening. The study demonstrates that carbon nanotubes, graphene oxide, and silica nanoparticles significantly enhance both mechanical and thermal properties of polymer composites, making them suitable for applications in industries such as automotive, aerospace, and electronics. Future research should focus on optimizing nanofiller concentrations and evaluating the long-term performance of these materials under real-world conditions.
