The boron nitride nanosheets (BNNS) was surface modified by γ-(2,3-epoxypropoxy) propytrimethoxysilane (KH560), and then epoxy resin/functionalized BNNS (EP/BNNS-KH560) composites were prepared by doping BNNS-KH560 into epoxy resin matrix. The structure and morphology of the functionalized BNNS were measured, and the properties of EP/BNNS-KH560 composites were studied. The results show that the surface of BNNS is grafted with KH560 successfully, which exhibits a transparent thin layer structure under transmission electron microscope. The addition of BNNS-KH560 with a wide energy level gap can maintain the high insulating properties, excellent dielectric properties, and mechanical properties of the composites, and improve their thermal stability. Additionally, the BNNS-KH560 can form a good heat conduction channel in epoxy resin matrix, and improve the thermal conductivity of the composites effectively. When the mass fraction of BNNS-KH560 in composites is 20%, the thermal conductivity of the composites can reach 0.51 W/(m·K).
