| Abstract Scope |
In this work a polymer blend system composed of polylactic acid (PLA) reinforced with a polyvinyl acetate (PVA)/graphene oxide (GO) composite was melt-compounded. PVA was used to facilitate incorporation of the GO into the composite because the GO was in an aqueous solution. It was found during the melt compounding process that a filament with a homogenous diameter could not be made due to phase separation of the two constituents. However, it was noted that pellets of the material could be made. Sample pools of different PVA/GO composite loading were made and the materials were characterized by tensile testing, dynamic mechanical analysis (DMA), and scanning electron microscopy (SEM). All test specimens were fabricated using fused granulate fabrication (FGF). The work presented here demonstrates an advantage of FGF that is not often highlighted, the ability to fabricate components from a material system that cannot be extruded into a filament. |
