The film responds fast to the applied voltage in orientation of LC. However, the response measured as transmittance after switching-off the applied voltage reveals the distinctive information on LC mobility-temperature relationship. The reorientation of LC after switching-off the voltage takes the longest time at 38 °C. The temperature coincides with Tgmeasured by DSC. The slowest response in terms of transmittance at 36 °C is attributed to the resonance developed between the polymer segments wobbling at Tgand LC returning to the state prior to switching-on. ？ 1994, Taylor & Francis Group, LLC.
