Abstract
AbstractThis work presents the synthesis of polypropylene/graphite nanocomposites by in situ polymerization using the catalytic system C20H16Cl2Zr (rac‐ethylenebis (indenyl)zirconium(IV)) dichloride/Methyoluminoxane (MAO). 60 nm graphite nanosheets (GNS) were obtained by means of the chemical exfoliation, thermal and ultrasound treatment. GNS previously treated with MAO were added into the reactor at percentages of 0.3, 1.0 and 2.2% (w/w) in relation to nanocomposite yields. The morphology of graphite nanosheets and nanocomposites was studied by Scanning Electron Microscopy (SEM). Moreover, the structural properties of natural graphite flake (NGF), graphite nanosheets (GNS) and nanocomposites were observed through the X‐Ray diffraction (XRD) analysis and by Transmission Electron Microscopy (TEM).
