Description:

The effect of self-assembled barium titanate (BT) aggregates in polyvinylidene fluoride (PVDF) matrix on the α‐β phase transition was investigated. The self-assembled BT/PVDF composites were prepared with and without dispersant in the self-assembled process. The addition of dispersants increased the average secondary particle area (S) of the BT particles and promoted the BT/PVDF/BT hetero-interface. FT-IR showed that the α‐β phase transition of the composites enhanced with increasing S. The Cole-Cole plot was estimated the existence of orientation polarization and interface polarization. According to these results, we proposed a BT/PVDF/BT hetero-interface model based on the double Schottky barrier model.
