The results of a study of linear and nonlinear dielectric properties, as well as calorimetric measurements of a ferroelectric composite (C6H16NBr)1-x/(PbTiO3)x with a volume fraction of lead titanate particles in a composite x = 0.1, 0.2, 0.3, are presented. It was shown that the addi-tion of lead titanate particles to diisopropylammonium bromide leads to a change in the sequence of structural phase transitions in diisopropylammonium bromide, an increase in the effective di-electric constant and tanδ. In the temperature range of 150-138 ° C, there are two C6H16NBr phases (ferroelectric P21 and non-ferroelectric P212121), the ratio of which depends on the frac-tion of lead titanate particles in the composite. |
