Preparation and Properties of Graphene/Polyamide 6 Composites by Melt Compounding

Abstract

In this paper, graphene was obtained by Oxidation-reduction method. The obtained graphene was characterized by XRD and FTIR. On this basis, graphene/polyamide 6(PA6) composites were prepared by melt compounding. The well-dispersed graphene nanosheets in PA6 matrix was investigated by SEM. The properties were characterized by XRD, DSC and TGA. The results showed that the α-phase of polyamide 6 induced into γ-phase by adding graphene. The crystallization temperature and the crystallinity of composites have been increased in some degree. Besides, the composite has a higher thermal stability.
