<p>Rolling is a mechanical processing technique commonly employed in polymer processing to modify the morphology, orientation, and dispersion of fillers within a polymer matrix. The polypropylene (PP) nanocomposites with rolling process are utilized to enhance the dispersion of nanofillers within the PP matrix and to induce alignment of both the polymer chains and nanofillers. This study investigates the influence of rolling on the mechanical behaviour of polypropylene (PP) nanocomposites reinforced with graphene (G) and hexagonal boron nitride (hBN). In this work, nanocomposite samples were subjected to controlled rolling to evaluate changes in tensile, impact, flexural strength and morphological characteristics. Results revealed that rolling not only improved filler alignment but also contributed to a denser microstructure with better stress distribution. The findings highlight that rolling can serve as an effective post-processing method to optimize the mechanical properties of PP nanocomposites, offering a cost-efficient route for advanced applications. This technique involves passing the nanocomposite material through rollers under controlled temperature and pressure, leading to compression and reorganization of the internal structure. The experimentation was carried out for thickness reduction (TR), representing low (20%), moderate (30%), and high (40%) which correspond to compression ratios (CR) of 1.25, 1.42, and 1.67, respectively.</p>
