Abstract:0-3 type PZT/PVDF piezoelectric composites were prepared by high-temperature-pressing techniques.The influence of different volume ratios on the dielectric and piezoelectric properties of PZT/PVDF composites was studied and compared with the theoretical values proposed by Furukawa et al.A higher piezoelectric and dielectri property of the composite was obtained when volume ratio of the modified PZT is 0.7.ln higher volume ratio composites.some piezoelectric particles appear to be in contact,the properties of piezoelectric and dielectric of the composites were higher because of the type of 0-3 (1-3) structure was formed.
Keywords:0-3 type modified PZT/PVDF,volume ratio,piezoelectric property,dielectric property
