The wollastonite was grafted with different silane coupling agents, which could improve interface adhesion. Wollastonite and modified wollastonite‐reinforced poly(ether ether ketone) (PEEK) composites were prepared by melt blending. The mechanical properties, rheology behavior, and thermal properties of the composites were investigated. The modified wollastonite‐reinforced PEEK composites exhibited better mechanical properties than the unmodified wollastonite‐reinforced PEEK composites based on good interfacial adhesion. The composites had lower activation volume and complex shear viscosity. Furthermore, the modified wollastonite‐reinforced PEEK composites had higher crystallization peak temperature ( T c ) and crystalline fraction (χ c ) compared with the unmodified wollastonite‐reinforced PEEK composites. This study shows that the traditional silane coupling agents could effectively improve the performance of PEEK composites. POLYM. ENG. SCI., 2011. © 2011 Society of Plastics Engineers
