The biodegradable polymeric nanocomposites were prepared by melting extrusion process using a twin-screw extruder machine. The influence of the RGO nanosheets incorporation on mechanical and thermal properties of PBAT/PLA blend was investigated by tensile Thermogravimetric (TG), X-Ray diffraction (XRD), differential scanning calorimetry (DSC), and tensile test analysis. Results showed that incorporation of the small amount ofRGO(0.1wt.%) ofRGOnanosheets in the blend matrix of PBAT/PLA resulted in an important gain of mechanical properties of the blend. This result indicates that a very small amount of RGO nanosheets addition in the PBAT/PLA can lead to obtaining materials with superior properties suitable for several industrial applications.631-639closedAccesspolymersgrapheneoxidesbiodegradationmechanical testsInvestigation on mechanical and thermal behaviours of PBAT/PLA blend reinforced with reduced graphene oxide nanosheetsCapítulo de livroCharacterization of Minerals, Metals, and Materials10.1007/978-3-030-36628-5_620000-0003-3546-1643https://orcid.org/0000-0003-3546-1643
