dc.description.abstract© 2021, The Author(s), under exclusive licence to Springer Nature B.V.Polylactic acid (PLA) is the most wide-scale investigated biodegradable and renewable under specific processing conditions thermoplastic polyester. As bioplastic material, it has the potential to be used as a substituent of conventional polymers derived from fossil fuel resources. The drawbacks possessed by PLA as poor thermal and electrical properties, mechanical brittleness, and ability to undergo polymer chain degradation in ambient medium could be overcome by incorporation of carbon nanofillers in the PLA matrix. Raman spectroscopy was used to study the effect of graphene nanoplatelets (GNPs) and multiwall carbon nanotubes (MWCNTs) on the nanocomposite molecular morphology and structure. The carbon nanofillers impact on the crystallinity of the melt blended hybrid material and the changes in the composite architecture were defined by applying of physical methods as X-ray diffraction (XRD) and differential scanning calorimetry (DSC). Thermo-gravimetric analysis (TGA) was implemented to outline the thermal properties of the nanocomposites. An excellent homogeneity and firmly expressed crystalline structure of the produced composite materials were disclosed. Tensile testing showed that coupling GNPs and MWCNTs has higher positive effect on ultimate tensile strength of the nanocomposites and lower influence on Young’s modulus of elasticity.
