Water ice is observed to order at the copolymer ferroelectric poly(vinylidene difluoride−trifluoroethylene) surface. The successful growth of crystalline thin films of water on these polymer surfacesimplicates water to polymer dipole interactions. These ice thin films are sufficiently ordered for experimentalidentification of the wave vector dependence in the electronic band structure of hexagonal ice. The significantband dispersion, of about 1 eV, suggests strong overlap of molecular orbitals between adjacent watermolecules in the ice film. The presence of dipole interactions with adsorbate water is consistent with thepossibility of water acting as a spectator to surface ferroelectric transitions in this system.
