Mechanical and Electrical Properties and Electromagnetic-Wave-Shielding Effectiveness of Graphene-Nanoplatelet-Reinforced Acrylonitrile Butadiene Styrene Nanocomposites

Polymer nanocomposites have attracted global attention as a metal replacement for electrical and electronic applications. Graphene nanoplatelets (GNPs) are widely used nanoreinforcement to enhance the functional structural properties of thermoset thermoplastic polymers. In present study, ABS were prepared by reinforcing 3–15 wt.% GNPs in steps 3 wt.%. The neat ABS+GNP nanocomposite specimens mechanical test using injection molding, followed extrusion, per American Society Testing Materials (ASTM) standards. It was found that modulus improved due reinforcement GNPs. Additionally, we noticed higher thermal stability faster heat-conducting path developed presence However, observed agglomeration at concentrations poor wetting with led deterioration nanocomposites. Moreover, 350 µm thick films manufactured compression extrusion method, investigated their conductivity, magnetic permeability, permittivity, electromagnetic-wave-shielding effectiveness. showed conductivity effective electromagnetic wave shielding absorption. 15 GNP-reinforced composite film maximum effectiveness 30 dB X-band.
