摘要：Graphene nanoplatelets coated by polyaniline (GNP@PANI) and ethylene-vinyl acetate (EVA) copolymer-high-density polyethylene (HDPE) were used for the first time to prepare high-performance antistatic composites through an effective method that combined solution mixing and melt blending. GNP@PANI nanocomposites were fabricated by in situ polymerization to improve the dispersion of graphene nanoplatelets (GNPs) in the EVA-HDPE matrix and the compatibility between the GNPs and the EVAHDPE matrix. The GNP@PANI nanocomposites and EVA were first prepared as a premix through solution mixing, and then, the premix and HDPE were prepared as highly antistatic composites through melt blending. The dispersion of the GNPs in the EVA-HDPE matrix and the compatibility between the GNPs and the EVA-HDPE matrix were confirmed by field emission scanning electron microscopy and transmission electron microscopy observations. The GNP@PANI-EVA-HDPE composites met the requirements for antistatic materials when the content of the GNP@PANI nanocomposites was 5 wt % with only about 1 wt % GNPs. (C) 2017 Wiley Periodicals, Inc.
