Graphene being 2D crystalline material has attracted broad and deep interest all over the world due to its good physical, chemical, mechanical and electrical property with high shape asymmetry. Fabrication of high-quality graphene is becoming increasingly important to work on its various properties and application prospects. Recent progress on the hybrid material-based nanomaterial has greater prospects in many applications. In this investigation, commercial graphite powder is preferred as the precursor and two different solvents showing different exfoliation efficiencies, i.e., N-Methyl-2-pyrrolidone and 1-Methylnaphthalene are employed as exfoliation media. Ball milling technique, known to have successfully produced nanomaterials in large scale, is employed in this work to produce multi- layered graphene sheets. Multi-layer graphene’s are made with high aspect ratio with modifications in process parameter. The exfoliated multi-layered graphene is incorporated as filler material with polypropylene matrix to develop polymer nanocomposites. The enhanced mechanical stability of the polypropylene/graphene nanocomposite and its respective morphology is studied in this work which has applications in photovoltaics, electronic devices and facial reconstruction.
