We synthsized a novel photoresponsive liquid crystalline (LC) elastomer (PLCE) via the acrylic diene metathesis polymerization. PLCE formed a nematic (N) phase below the isotropization temperature (TNI = 145 °C) and the N phase turned to the glassy N phase below the glass transition temperature (Tg = 24 °C). PLCE films were reversibly deformed by exposing to ultraviolet (UV) and visible light. Additionally, we demonstrated the rewritable micro-patterned PLCE film. Because of the wireless remote-controlled actuating behaviours of PLCE combined with its excellent processability, PLCE can be applied in optoelectronic and bio-mimetic devices. This work was mainly supported by the Converging. Research Center Program (2013K000404) and BK21 PLUS Program, Korea. |
