3-Mercaptopropyltrimethoxysilane (MPTMS)-ethanol solution treated nitrile butadiene rubber/nanodiamond (NBR/ND) polymer nanocomposites were prefabricated. The nanodiamond (ND) and modified nanodiamond (MND) were characterized. The results show that the pristine ND is provided not only with high specific surface area, but also with abundant active organic groups, especially hydroxyl and carboxyl groups, which confirms the hydrophilic properties of nanodiamond. The morphology of the fracture surfaces of NBR/(M)ND nanocomposites are studied by high resolution scanning electron microscopy. The dynamic rheological properties of NBR/(M)ND nanocomposites were characterized by rubber processing analyzer. The NBR/MND composites exhibited superior mechanical property attributing to the stronger interfacial interaction via covalent bonding between MND and NBR molecules.
