Abstract :
The Chemical vapor deposition (CVD) graphene/ BaTiO3(BT)/polyvinylidene fluoride (PVDF) nanocomposites were prepared by powder metallurgy. SEM results show that CVD GS and BT are well dispersed within the PVDF matrix. Compared with binary CVD graphene sheets (GS)/PVDF and BT/PVDF nanocomposites, the dielectric properties of the CVD GS/BT/PVDF nanocomposites exhibit a better dielectric performance. The powder metallurgic method is an effective way to fabricate multiple components composites and avoid serious inhomogeneity and aggregation of fillers in the polymer matrix.
