Toughness modification of polypropylene (PP), a widely used polymer in industry, is an important factor in overcoming mechanical limitations and extending its scope of application. In the present work, we utilized a combination of nanoparticle and elastomer techniques to enhance the toughness of PP. Accordingly, the nanocomposite blends, including PP, ethylene octene copolymer (EOC), and multi-walled carbon nanotubes (MWCNTs), were pre-
