Characteristics and Mechanical Properties of Graphene Nanoplatelets-Reinforced Epoxy Nanocomposites: Comparison of Different Dispersal Mechanisms

The preparation of polymer-based nanocomposites requires considerable time (i.e., the dispersal nanomaterials into a polymer matrix), resulting in difficulties associated with their commercial use. In this study, two simple and efficient dispersion methods, namely planetary centrifugal mixing three-roll milling, were used to enable graphene nanoplatelets disperse uniformly throughout an epoxy solution 0, 0.1, 0.25, 0.5, 1.0 wt.%) allow subsequent nanoplatelets/epoxy nanocomposites. Measurements mechanical properties these nanocomposites, including ultimate tensile strength, flexural modulus, evaluate methods. Dispersing resin by not only required shorter process but also resulted more uniform than that milling. addition, compared traditional was method for epoxy-based
