液晶／高分子複合膜及び液晶／光重合性モノマー混合物のTSC挙動に関する研究

Thermally stimulated current(TSC) behaviors of liquid crystal(LC)/polymer composite films and LC/monomer mixtures have been investigated. The composite films are formed by the photo-polymerization induced phase separation process. The samples used were mixtures of the fluorinated liquid crystals having tolane linking group and the diacrylate monomer, and the composite films after photo-polymerization. In TSC curves of the liquid crystal/monomer mixtures with 65-85mol% of LC fraction, 3 kinds of peaks were observed at -48(peak A), -55(peak B), and -62°C(peak C). The peak A was assigned as the melting point of the monomer-rich phase and the peak C as T g of the liquid crystalline phase, whereas there is no clear-cut explanation for the peak B. TSC curves of LC/polymer composite films showed a tendency similar to the LC/monomer mixtures.
