Since carbon nanomaterials (carbon nanotubes and graphite nanoplatelets) with large surface area and high aspect ratio exhibit a unique combination of thermal, mechanical, and electrical properties, they are envisaged as ideal reinforcing fillers to improve the various properties of conventional polymers. Recently, much attention has been also paid to polylactide (PLA) as an eco-friendly biomass-based thermoplastic polymer, because the exhaustion of fossil resources and the environmental pollution have become severer than ever. Although PLA has balanced properties of thermal plasticity, mechanical strength, and compostibility for short-term commodity applications, the further improved thermal and mechanical properties of PLA are required for long-term high performance applications. In some cases, the low electrical resistivity of PLA is necessary for the electrostatic dissipation and/or electromagnetic insulation in advanced applications. In the presentation, the structure-property relationship of PLA-based hybrid nanocomposites including carbon nanotubes or graphite nanoplatelets will be discussed. |
