Interfaces can stabilize ferroelectric phases in confined polymers.

Different confinement geometries affect ferroelectric stability.

Interface effects are crucial for ferroelectric behavior in polymers.

Abstract

The effect of interfaces and confinement in polymer ferroelectric structured is discussed. Results on confinement under different geometries are presented and the comparison of all of them allows to evidence that the presence of an interface in particular cases stabilizes a ferroelectric phase that is not spontaneously formed under normal bulk processing conditions
