Synergistic Effect of Graphene Nanoplatelets and Multiwall Carbon Nanotubes Incorporated in PLA Matrix: Nanoindentation of Composites with Improved Mechanical Properties

The synergistic effect of two carbon nanofillers on the mechanical properties PLA-based nanocomposites was investigated in present work. Polylactic acid is relatively brittle semi-crystalline polymer which selected for composite matrix because its biodegradable properties. It reinforced with graphene nanoplatelets and multiwall nanotubes by means melt mixing preparation method. Nanohardness Young’s modulus smooth nanocomposite samples received 3D printing were defined nanoindentation experiments using Berkovich-type pyramidal nanoindenter. found that compounds, incorporated both structure, exhibit better performance compared to loaded a single nanofiller. Different techniques sample applied order see influence preliminary processing nanomechanical specimens. X-ray diffraction Raman spectroscopy used study structural features pristine nanomaterials.
