Efficient preparation and characterization of graphene based on ball
Introduction. Graphene is a nanomaterial composed of carbon atoms formed in sp 2 hybridized orbitals and connected by covalent bonds in a hexagonal honeycomb nested lattice with an ideal two-dimensional crystal structure [1]. The single-layer thickness of graphene is only 0.3354 nm, making it the thinnest material ever Ball-milling is a common technique in the powder production industry to acquire grains of specific dimensions. This is performed by placing solid materials of interest in a carbon tape with a uniform layer of the graphene materials under study. Raman spectroscopy analysis was performed using a confocal micro-Raman LabRam HR instrument fromBall-Milled Sulfur-Doped Graphene Materials Contain
