Polyamide 6 (PA6) nanocomposites with electrically and thermally conductive were formulated via melt processing of PA6 and different inclusion of reduced graphene oxide (RGO). These nanocomposites showed that the small percolation threshold and the perfect formation of conductive link form with 0.5 wt% and ̴3.0 wt% of RGO respectively. Crystallization examination confirmed that RGO enabled the crystallization of PA6 structure mostly through speeding up the formation of crystal nucleus, reaching

With the dynamic rheological testing, frequency-independence of G' and abruptly decrease phase angle at the small-frequency area via RGO content of 2.0 wt% specify the alteration state from liquid-state to solid-state rheological performance, and validate the development of percolation link structure with RGO in the function of a crosslinking factor. The progress of fire-retardant characteristics of PA6 was attained due to the inclusion of RGO owing to the improver in the PA6 structure. Morphological research showed that RGO was spread consistently in the PA6 structure. From the outcomes of cone calorimetry outcomes, the flame-retardant characteristics of PA6 were promoted with the addition of RGO in the PA6 structure. These tests show substantial capacity for the bulk manufacture of electrically conductive polymer/RGO nanocomposites.
