An organic plastic ferroelectric with high Curie point.

ABSTRACT: Plastic ferroelectrics, featuring large entropy changes in phase transitions, hold great potential application for solid-state refrigeration due to the electrocaloric effect. Although conventional ceramic ferroelectrics (e.g., BaTiO₃ and KNbO₃) have been widely investigated in the fields of electrocaloric material and catalysis, organic plastic ferroelectrics with a high Curie point (T _c) are rarely reported but are of great importance for the sake of environmental protection. Here, we reported an organic plastic ferroelectric, (-)-camphanic acid, which crystallizes in the P2₁ space group, chiral polar 2 (C₂) point group, at room temperature. It undergoes plastic paraelectric-to-ferroelectric phase transition with
