Dependence of Characteristics of Polymer-Stabilized Ferroelectric Liquid Crystals on Monomer Materials

抄録

Polymer-stabilized ferroelectric liquid crystals (PSFLCs), in which a photocurable mesogenic monomer is doped into a ferroelectric liquid crystal and a UV photocure is carried out in the SmC^* phase under the application of a monopolar DC electric field, show the monostable half-V-shaped electrooptical characteristics. In this research, we have investigated the dependence of the electrooptical characteristics of PSFLC on the type of monomer such as the number of functional group and the presence of chirality. As a result, it is found that the response time of PSFLC with relatively soft polymer is shorter than that with hard polymer.
