Electrical and Mechanical Properties of Pa11 Blended with Nanographene Platelets Using Industrial Twin-Screw Extruder for Fused Deposition Modeling

 

The specific objective of this research is to produce and characterize polyamide 11/ nanographene platelets nanocomposites that have improved electrical conductivity for electrostatic charge dissipation applications. Polyamide 11 and nanographene platelets were blended using industry size co-rotating twin-screw extrusion. Tension and electrical resistivity test samples for neat PA11, 3 wt.% PA11/NGP and four different types of metal filled PLA were prepared using fused deposition modeling on Lulzbot Taz 4 3D printer. Electrical resistivity was measured using the Hioki Megaohmmeter Instrument. Mechanical characterization includes tensile test of the samples. The only material system that was qualified for electrostatic charge dissipation (ESD) applications was conductive graphite PLA. The recommended range of electrical resistivity for ESD applications is in the range of 1010 – 1011 -cm.
