Polyamide 6 (PA6) and acrylonitrile butadiene styrene blend reinforced by graphene nanosheets (GNs) nanocomposites were prepared by batch system followed by hot compression to get samples for different tests. A low amounts of graphene were used (1, 2, 3, 4 wt%), with this selected loading range, the mechanical properties (Young's modulus) have increased linearly with GNs contents. However, it is observed stability in the tensile strength. The electrical and rheological properties are well characterized and have shown that the evolution of the properties runs through a threshold loading charge. The results are related to the blends morphology, and SEM images showed selective preferential localization in the polyamide 6 phase. Moreover, the presence of GNs in the blends has reduced the surface tension between the two polymers. POLYM. COMPOS. 37:998–1006, 2016. © 2014 Society of Plastics Engineers

Abstract Nanocomposites of poly(vinylidene fluoride) (PVDF) with chemically reduced graphene nanosheets (GNs) were prepared by melt mixing method and their structure and morphology characterized by SEM analysis. The addition of GNs in the PVDF matrix resulted in changes of the crystallization and melting behaviors. Furthermore, increasing GNs content led to improved thermal stability of the PVDF nanocomposites in air and nitrogen, as well as significant increase in tensile and flexural properties. The nanocomposites' rheological behavior is also affected by the GNs' content. Using oscillatory rheology to monitor the GNs' dispersion, it was found that as the GNs loading increase, the Newtonian behavior disappears at low frequency. This suggests a viscoelastic behavior transition from liquid‐like to solid‐like, with greater GNs content and more homogeneous dispersion resulting in a stronger solid‐like and nonterminal behavior. By using the melt mixing method to disperse GNs, the properties of PVDF are enhanced due to the better dispersion and distribution of GNs throughout the matrix. This improvement could broaden the applications for PVDF nanocomposites. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
