A study on polarization properties of the carbon black modified 0-3 cement-based piezoelectric composites

Abstract:

A carbon black modified 0–3 cement-based piezoelectric composite was fabricated with piezoelectric ceramic [0.08Pb(Li1/4Nb3/4)O•0.47PbTiO3•0.45PbZrO3], sulphoaluminate cement and carbon black by compressing technique. The influences of poling conditions on the piezoelectric and dielectric properties of the composites were investigated. The results show that the higher poling electric field, the longer poling time and the higher poling temperature, the composites have the higher piezoelectric strain factor d33, piezoelectric voltage factor g33, dielectric constant εr and dielectric loss tanδ. At the same time, the carbon black modified composites are polarized more easily than the unmodified composites, and have better piezoelectric and dielectric properties. Meanwhile, the optimum poling conditions were obtained, and the optimum poling field E, poling time t and poling temperature T were 4 kV/mm, 20 min and 80 °C.
