Nanodiamond (ND) has recently attracted much attention for its outstanding mechanical and other interesting properties. Surface functionalization of ND is necessary for applications in polymers. In this study, ND particles were functionalized with amine by covalent linking of triethylene tetramine, and further grafted with epoxy which was cured with amine curing agent. The particle dispersion and mechanical properties of epoxy/ND nanocomposites were evaluated. Both fracture toughness and storage modulus of epoxy resin were significantly improved with a low loading of ND‐NH 2 particles. The morphological structure of the epoxy/ND nanocomposites was examined, and toughening mechanism was explored. POLYM. COMPOS., 35:2144–2149, 2014. © 2014 Society of Plastics Engineers
