摘要
The ferroelectric properties of ferroelectric liquid crystals (FLCs) during thermal phase transition in the surface-stabilized ferroelectric liquid crystal (SSFLC) cells were examined. The coercive electric field (E-c) and remanent polarization (P-r) changed with increasing temperature. These temperature-dependent variations of E-c and P-r were in agreement with the differential scanning calorimetry results. Moreover, the fatigue characteristic of the SSFLC cells was examined. No polarized fatigue was observed after 1 x 10(6) cycles of polarization switching, because FLCs may have the self-repair property for structural and interfacial defects.
