Abstract: A toughened thermoplastic composition containing thermoplastic polyurethane, carbon nanostructures, and graphite microparticles coated with at least one metal. The toughened thermoplastic composition is an injectable moldable grade thermoplastic composition, with developed processing properties compatible with fused filament fabrication additive manufacturing, EMI shielding, and electrical grounding. The composition contains an electrically conductive polymer composite, the composite containing: at least one thermoplastic material containing thermoplastic polyurethane; at least one electrically conductive material containing carbon nanostructures; and at least one graphite microparticle coated with at least one metal.

Abstract: An electrically conductive thermoplastic composition comprised of at least one thermoplastic polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) polymer, at least one electrically conductive material containing carbon nanostructures or nanomaterials, and optionally at least one ethylene/alkyl-(meth)acrylate copolymer. The conductive thermoplastic composition can be injection molded and/or printable using additive manufacturing techniques.
