摘要

Abstract

Simultaneous functionalization and reduction of graphene oxide (GO) is realized by refluxing of GO suspension with polyetheramine (D2000) followed by thermal treatment at 120 ℃. Compared to GO

the D2000-treated GO (GOD2000) becomes hydrophobic

thermally stable and highly conductive with an electrical conductivity of 11 S/m

which is almost 8 orders of magnitude higher than that of GO. Due to the high conductivity and improved dispersion of GO-D2000

its epoxy nanocomposites exhibit a sharp transition from electrically insulating to conducting with a low percolation threshold of 0.71 vol%. With 3.6 wt% GO-D2000

the glass transition temperature of the epoxy nanocomposite is 27 K higher than that of neat epoxy.
