スポンサーリンク
概要
- 論文の詳細を見る
The out-of-plane (polar) anchoring strength at the interface between pentylcyanobiphenyl (5CB) and alignment layer possessing azo-group in polyimide main chain (P3) was measured using the High Electric Field (HEF) method^<[1-2]>. The anchoring energy was the order of 10^<-4>J/m^2, and that of rubbed P3 was about two times larger than that of pholoaligned P3. A characteristic temperature dependence in the anchoring energy was found to exist near the clearing temperature of 5CB particularly for the photoalignment layer.
