▎ 摘　　要

Based on the industrialized reduced graphene oxide (RGO) product, MC nylon-6/RGO composites were in situ synthesized through anchoring effect of polyetheramine (PEA). Nylon-6 chains were confirmed to intercalate into RGO layers with high grafting ratio by formation of covalent bond and intermolecular hydrogen bond. By presence of PEA, RGO was well exfoliated by the nylon-6 chains and the average layer thickness increased remarkably. Moreover, the stacking of RGO layers was much more weakened and exhibited almost monolayer homogenous dispersion state in the matrix, resulting in the establishment of the electrically conductive network with a low threshold percolation.
