    The effect of graphene dispersion on the mechanical
    In this study, two different specimens with the poorly and highly dispersed graphene were prepared depending upon whether a ball mill procedure was used during the dispersion process or not. Discrepancies in the thermal, electrical and mechanical properties of graphene/epoxy composites with different graphene dispersion were

    Edge-carboxylated graphene nanosheets via ball milling
    Abstract. Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical appliions. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice.

    Reduced graphene oxide synthesis by high energy ball
    Graphene oxide is transformed to reduced graphene oxide by high energy ball milling in inert atmosphere. The process of ball milling introduces defects and removes oxygen functional groups, thereby creating the possibility of fine tuning the band gap of all intermediate stages of the structural evolution.

    Preparation of Colloidal Dispersions of Graphene Sheets
    Figure 1: Schematic illustration for the creation of graphene from multilayered graphite by using wet ball-milling: (a) GNs dispersed in solvent are delaminated by mill balls in grinding process; (b) graphene sheets are formed in situ in solvent. The arrows indie the shear forces applied to graphite platelets.

    Preparation of graphene by exfoliation of graphite using
    Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multi-layered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,N-dimethylformamide (DMF) and exfoliated by shear-force-dominated ball milling carried out in a planetary mill. After high-speed
