摘要：

Graphene nanoplatelets/Boron nitride (GNPs/BN) nanocomposites were prepared by precursor-assisted hightemperature sintering technique using carbamide (CH4N2O) and boric acid (H3BO3) at the temperature as low as 950 degrees C. The multilayer and single BN coverage combine with GNPs through van der Waals interplanar interaction without damaging the structures of GNPs. Specifically, GNPs/BN with oxidation temperature of 730 degrees C shows remarkable thermal stability compared to the original GNPs, indicating an increase of 31% in antioxidant performance, which provides great potential for GNPs in high-temperature heat-insulating coatings, inorganic refractories and heat-resisting binder, etc.
