Abstract
A kind of high-performance bismaleimides composite has been fabricated using carbon nanotubes as filler, in which the carbon nanotubes was grafted by hyperbranched triazine compound (HPTC-CNTs). The investigation of properties the composites show that the addition of the appropriate content of HPTC-CNTs can enhance the tribological properties. It’s worth noting that when the content of HPTC-CNTs is 0.6 wt. %, the frictional coefficient and the wear rate decrease by 29.5% and 91.8% respectively compared to neat BMI. Scanning electron microscope（SEM）reveals that wear mechanism of neat BMI is mainly fatigue wear, but it turns adhesive mainly wear after the incorporation of HPTC-CNTs. The main reason can be the good dispersability and compatibility of HPTC-CNTs in the bismaleimides matrix.
