Multiwalled carbon nanotubes/cyanate ester composite using epoxy group as a bridge was prepared. After a two‐step functionalization, the epoxy groups were introduced on the surface of multiwalled carbon nanotubes (MWNTs) successfully, which was confirmed by X‐ray diffraction and Fourier transform infrared spectra. The mechanical and thermal properties of the cured cyanate ester resin and MWNTs/cyanate ester composites were examined by mechanical tests, scanning electron microscopy, and dynamic mechanical thermal analysis. The results showed that 2 wt% functionalized MWNTs can enhance the flexural strength and impact strength significantly and increase the glass transition temperature ( T g ) slightly. POLYM. ENG.
