ABSTRACTA phase-field model for predicting the domain structure evolution in constrained ferroelectric thin films is developed. It employs an analytical elastic solution derived for a constrained film with arbitrary eigenstrain distributions. In particular, the model is applied to the domain structure evolution during a cubic→tetragonal proper ferro- electric phase transition. The effect of substrate constraint on the volume fractions of domain variants, domain-wall orientations, and domain shapes is studied. It is shown that the predicted results agree very well with existing experimental observations in ferroelectric thin films.

Flory–Huggins theory combined with experimental tests and phase-field simulation proves that electrospinning improves the homogeneity and Eb in composite films, and MS can limit the ferroelectric relaxation of PVDF and significantly increase Ue and η.
