title: Durable micropatterns obtained from dissipative structures in liquid crystals.
abstract: A diffraction grating or more complex optical phase object can be formed and preserved from a crosslinked liquid crystalline film. The gratings are formed from electrically conductive liquid crystals, which show a rich variety of dissipative structures depending on the applied AC field strength and frequency. Addition of a crosslinking agent and irradiation with UV light thereby "freezes" the structures.
