Increase of Azimuthal Anchoring Energy and Thermal Stability at Homogeneously Orientated Liquid Crystal/Polymer Interface

概要
- 論文の詳細を見る
A surface memory effect appears on isotropic polymer surfaces when the polymer surface is exposed to a homogeneously orientated nematic liquid crystal(LC), and an azimuthal anchoring energy of the surface increases with exposure time. The increase of the anchoring energy is also observed in the homogeneous LC cell with rubbed polymer substrates, but not in the twisted nematic(TN)cell. Alignment surfaces in the homogeneous LC cell become stable against heating above the glass transition temperature of the polymer, in contrast to the thermal instability in the TN cell. These results reveal that the LC bulk orientation actively influences the polymer molecular orientation at the LC/polymer interface.
