Abstract

This paper reports results of a detailed study of the effects of the crystallographic orientation on the performance of the 2-2 parallel-connected composites based on relaxor-ferroelectric single crystals of 0.72Pb(Mg_1/3Nb_2/3)O₃-0.28PbTiO₃. These single crystals are poled along one of the following directions in the perovskite unit cell: [111] (single-domain state), [001] and [011] (polydomain states). The effect of the orientation of the main crystallographic axes in the single-crystal component on the hydrostatic piezoelectric coefficients d_h , e _hand g _h, squared hydrostatic figure of merit d _h g _h and hydrostatic electromechanical coupling factor k _h of the composites is studied for three cases of the poling direction of 0.72Pb(Mg_1/3Nb_2/3)O₃-0. 28PbTiO₃. Maximum values of the hydrostatic parameters in the 2-2 0.72Pb(Mg_1/3Nb_2/3)O₃-0.28PbTiO₃ / polyvinylidene fluoride composites ^are d_h = 372 pC / N, g_h = 284 mV.m / N, d_h g_h = 33.8.10 -₁₂Pa^-1, and k_h = 0.361 (in the presence of the [011]-poled single crystal), and e_h = 45.1 C / m² (in the presence of the [111]-poled single crystal). The inequality k₃₃ / |k_3j | ≥ 5 (j = 1 and 2) is valid for the composite based on the [111]-poled single crystal under specific conditions. The composites exhibit remarkable properties, and the elastic and piezoelectric anisotropy of the single-crystal component (either [111]- or [011]-poled) plays an important role in achieving the large hydrostatic parameters
