Abstract

In this work, the effect of a polar nanoporous matrix of barium titanate on the phase transition temperatures of embedded thiourea was investigated. An increase in the ferroelectric-paraelectric transition temperature of embedded SC(NH2)2 has been detected. This is explained by the fact that due to the higher coefficient of thermal expansion for thiourea compared to barium titanate, when the temperature drops from room temperature (not stressed) to 178 K (stressed), the compression of thiourea crystals occurs faster than barium titanate.
