Abstract The microstructure of PAI/EP blends was adjusted by nano-silica (SiO₂). The reaction mechanism, microstructure and friction properties were analyzed by infrared spectroscopy (IR), scanning electron microscopy (SEM), MRH-3G friction and wear tester. The results showed that the nanoparticles greatly broadened the co-continuous range between the two phases when the nanoparticles were 3wt% EP in the EP/PAI blends,and improved the stability of the co-continuous structure between the two phases, improved the friction performance greatly and reduced the friction coefficient and the wear rate of the composites. At the same time, the co-continuous structure became more smaller due to the double-seepage effect and the directional aggregation of the nano-particles, which shortened the running time of the friction process and reduced the true contact area with the metal substrate. The increase of the nanofiller reduced the friction coefficient and the wear rate. The friction coefficient decreased by 46.8%, the wear rate decreased by 37.5%.
