摘要：

Novel high-dielectric-permittivity poly(vinylidene fluoride) (PVDF) /polypropylene (PP) blend composites were prepared via a blending technology, and their dielectric properties were studied over wide ranges of temperatures and frequencies. To improve the interface bonding between PVDF and PP, a suitable compatibilizer, polypropylene-graft-maleic anhydride (PP-g-MAH), was employed. The results showed that the concentration of PVDF in the composites dominated the changes in the dielectric properties and that the use of PP-g-MAH could improve the interface interaction between PVDF and PP, resulting in an increase in the dielectric permittivity.
