  • Effect of atmosphere on the mechanical milling of natural

    Natural graphite was ball milled in a vibratory and a planetary mill under different atmospheres. Its microstructure was found to evolve very differently when milled in oxygen and in an inert atmosphere. This phenomenon is most pronounced when it was milled in a planetary mill where the deformation forces are mainly shear in nature.

  • Synthesis of graphene nanoflakes by grinding natural

    Natural graphite is a soft material that conventional milling methods fail to grind into nanoparticles. We found that adding NaCl into graphite during milling allows obtaining graphene nanoflakes of about 50 200nm 2 as evidenced by Transmission Electron Microscope (TEM). NaCl particles are substantially brittle and harder than graphite serving as milling In this study we prepared large anionic graphite flakes ( 10 μm) by salt-assisted ball milling as well as natural graphite flakes of the same size for comparison. During the LPE process centrifugation speed and solvent type have dominant effects on graphene concentration and quality (e.g. size and thickness) so we investigated these
