Abstract
0-3 connectivity piezoelectric composites lead zirconate titanate(PZT)/ polyvinylidene fluoride(PVDF) were prepared. Crystallininity and microstructure of the samples were characterized by SEM, FTIR and WAXD. The results indicated that the PZT powder was blended with non-crystalline phase of PVDF. The composites presented different net-morphology. PVDF existed as $\alpha$ crystalline phase in the composites. The composites presented island type structure with low content of PZT and hard sphere stack in irregular type with high content of PZT.
