Abstract: Polyamide 6 (PA 6) is an engineering thermoplastic that can be used to develop polymer nanocomposite with high potential in electrostatic discharge applications. By the incorporation of nanofillers in PA 6 to enhance multifunctional properties, PA 6 nanocomposites can serve as technological alternatives to commercial thermoplastics for 3D printing via fused deposition modelling (FDM). Hence, this study evaluated the mechanical and electrical properties of 3D printed PA6 nanographene composites for electrostatic discharge applications. 2, 4 and 6 wt.% of Graphene Nanoplatelets (GNP) was compounded with PA6 using co-rotating twin screw extruder to produce 1.75mm diameter monofilaments for FDM 3D printing. The test samples were printed using commercial-off-the-shelf (COTS) 3D printer, Lulzbot TAZ 6 FDM printer. Morphology, mechanical and electrical characterization was carried out according to their respective ASTM standard. An improvement in tensile and flexural properties were observed with an increase in nanographene addition, and a maximum improvement of 61.4 and 55.9% in tensile and flexural modulus respectively was recorded at 6wt% loading level. Electrical conduction of the insulative polyamide 6 matrix was enhanced by an appreciable reduction of its volume resistivity to 1011 Ω.cm by 2wt% nanographene loading, which seems promising for manufacturing static discharge products.
