▎ 摘　　要

In this paper, a novel graphene-based inorganic organic hybrid flame retardant (GFR) was prepared via sal gel reaction of FGO and phenyl-bis-(triethoxysilylpropyl) phosphamide (PBTP) and characterized by FT-IR, XPS, XRD, TGA and AFM. The influence of the GFR on the thermal stability and flame retardance of epoxy resin composites were characterized by TGA, LOI as well as micro-cone, which indicated that GFR brought a good effect in enhancing the residual char and flame retardance of epoxy composites. The dynamic mechanical properties and electrical properties of EP composites were also analyzed. (C) 2013 Elsevier Ltd. All rights reserved.
