Abstract :
The purpose of this research is to investigate the Rheological, Thermal and Morphological properties of polypropylene with Styrene-Butadiene nanoelastomer (nSBR) and Graphene nano Oxide (nGO). From the nanocomposites homogenized in the Internal Mixer based on the test design table, SEM morphology, DSC thermal properties were tested. SEM images showed that uniform dispersion and proper interactions between nanoparticles and PP were established. SEM observations of the fracture surface of the composites show that the dispersion of nGO and nSBR in the PP/nSBR/nGO composite happened homogeneously. DSC analysis shows that the crystallinity peaks shift to higher temperatures and the crystallinity of pure PP changes from 117.2 °C and 117.94 °C at the optimal values of PP/nGO/nSBR composite. By adding optimal amounts of nanoparticles to PP, the maximum melting temperature (Tmp) and maximum crystallization temperature (Tcp) increase by 2.5% and 0.8%, respectively, compared to pure PP. The results of thermal analysis show that PP/nSBR/nGO composite has higher thermal stability than pure PP.
