A ferroelectric crosslinkable liquid crystalline copolysiloxane exhibiting broad chiral smectic C * and smectic A phases was synthesized and aligned by spin‐coating from solution. The homeotropic orientation of the mesogens was checked by polarizing microscopy and X‐ray scattering measurements. Crosslinking in the smectic A phase using UV‐irradiation stabilizes the spin‐coated films mechanically and fixes the monodomain orientation of the smectic A phase. Freestanding Ferroelectric Elastomer Films (FFEF) can be obtained by removing the substrate.
