PHASE TRANSITIONS IN COMPOSITES BASED ON DIISOPROPYLAMMONIUM CHLORIDE AND LEAD TITANATE

The paper presents the results of studies of the dielectric properties of (DIPAC)1-x/(PbTiO3)x composites with a volume fraction of lead titanate in composite x from 0.10 to 0.40. It was shown that the addition of lead titanate to diisopropylammonium chloride leads to an increase in the dielectric c...

Description
Summary:The paper presents the results of studies of the dielectric properties of (DIPAC)1-x/(PbTiO3)x composites with a volume fraction of lead titanate in composite x from 0.10 to 0.40. It was shown that the addition of lead titanate to diisopropylammonium chloride leads to an increase in the dielectric constant and the appearance of additional phase transitions during heating and cooling. The appearance of a new phase transition is explained in the framework of the Landau-Ginzburg theory, taking into account the dipole-dipole interaction between the components.
