Piezoelectric SbSI: Polymer composites

Abstract

Abstract Following the principle of connectivity in two phase systems, composites of SbSI and Spurrs epoxy in 1:3 and 3:3 modes were prepared. Piezoelectric strain coefficients d 33 and d h, and dielectric constant K were measured over a temperature range encompassing the transition temperature. Interactions between the polymer and SbSI cause a shift in the dielectric peak to higher temperatures. The hydrostatic voltage coefficient g h, ≃ 110 × 10−3 m 2/C and hydrophone sensitivity d h·gh ≃ 10−10 m 2/N are substantially higher than those of SbSI single crystals and most other piezoelectrics.
