Effect of SiO2 grafted MWCNTs on the mechanical and dielectric properties of PEN composite films

- MWCNTs were grafted successfully by SiO2.
- The surface modified MWCNTs-SiO2/PEN composite films possess high mechanical properties and excellent dielectric properties.
- The composites containing such two deferent nanoscale materials were researched by TEM and SEM.
- The interface adhesion was characterized by rheological test.
