Physico-chemical Characterization of PLA-based Composites Holding Carbon Nanofillers

Polylactic acid (PLA) is the most wide-scale investigated biodegradable and renewable under specific processing conditions thermoplastic polyester. As bioplastic material, it has potential to be used as a substituent of conventional polymers derived from fossil fuel resources. The drawbacks possessed by PLA poor thermal electrical properties, mechanical brittleness, ability undergo polymer chain degradation in ambient medium could overcome incorporation carbon nanofillers matrix. Raman spectroscopy was study effect graphene nanoplatelets (GNPs) multiwall nanotubes (MWCNTs) on nanocomposite molecular morphology structure. impact crystallinity melt blended hybrid material changes composite architecture were defined applying physical methods X-ray diffraction (XRD) differential scanning calorimetry (DSC). Thermo-gravimetric analysis (TGA) implemented outline properties nanocomposites. An excellent homogeneity firmly expressed crystalline structure produced materials disclosed. Tensile testing showed that coupling GNPs MWCNTs higher positive ultimate tensile strength nanocomposites lower influence Young’s modulus elasticity.
