Evaluating the Electrical Conductivity and Resistivity of Carbon Nanostructures Embedded in the PLA Matrix
Keyword(s):
In this work, we evaluated the fabrication and three-dimensional printing (3DP) of conductive filaments intended for designing electronic circuits using fused filament fabrication (FFF). For this 15 wt. % of graphene (GR), carbon black (CB) and carbon nanotubes (CNTs) were embedded into thermoplastic polylactic acid (PLA) resin matrix. Measurements of electrical resistance and conductivity, SEM, DSC, and XRD analysis were used to characterize the materials. The resistivity of the polymer nanocomposites was found to be between 0,7 and 1,4 Ω/cm and conductivity ranging between 0,71 and 1,42 S/cm, respectively.
