Azobenzene-based main-chain liquid crystalline (LC) polymer (PLCP) was newly synthesized via acrylic diene metathesis polymzerization. Utilizing the combined techniques of differential scanning calorimetry, cross-polarized optical microscopy and wide-angle X-ray diffraction, it was realized that PLCP formed a nematic (N) phase below the isotropization temperature and the N phase turned to the glassy N phase below the glass transition temperature. By applying light and/or heat, we successfully demonstrated the rewritable UV-patterned PLCP film as well as the mechanical deformation of the uniaxially oriented PLCP microfiber. This work was mainly supported by the Human Resource Training Project for Regional Innovation and the Converging Research Center Program (2011K000776) of Korean government. |
