Surface modification of perovskite ceramic BZT-BCT-filled PVDF-HFP composite films was synthesized/prepared using the solution-casting process. The effect of surface modification in perovskite-type ceramic-based polymer composites has been examined based on its end-use applicability. The morphology of the composite demonstrates that surface hydroxylation evenly dispersed the BZT-BCT ceramic particles in the polymer matrix (PVDF-HFP). The findings suggest that the presence of the hydroxyl group formed the linkage with the filler which is responsible for the interfacial contact of the hydroxylated fillers and the polymer matrix. It is pertinent to mention here that the hydroxyl-treated filler surface-based polymer composite has superior dielectric and ferroelectric characteristics with lower dielectric loss. The energy storage density value for the composite having surface-treated filler particle is much higher as compared to untreated BZT-BCT particle. These findings provide a new way for increasing dielectric energy.
