▎ 摘　　要

Graphene nanoplatelets (GNPs) are two-dimensional carbon structure materials with single or multilayers graphite plane which possesses attractive characteristics including high electrical conductivity, high modulus, high strength, high thermal conductivity and high specific surface area. In this study, the GNPs were modified by maleic anhydride (MA) and vinyltrimethoxysilane (VTMOS), and then reinforced carboxy NBR (XNBR) to prepare GNPs/nitrile rubber (XNBR) nanocomposites. The modified GNPs were characterized by Fourier Transform Infrared Spectrometry (FT-IR), Raman spectroscopy. The properties of GNPs/XNBR nanocomposite such as thermogravimetric analysis (TGA), thermal conductivity and mechanical properties were investigated. The experimental results show that the successful modification of GNPs can improve the properties of the nanocomposites.
