Fast photo- and electro-optical switching of the polymer- stabilised cholesteric liquid crystal composite prepared by the template method
Original language description
Multifunctional cholesteric liquid crystalline (LC) polymer-stabilized composite with photo- and electro-controllable photonic band gap was prepared and its fast photo- and electro-optical switching was demonstrated. The composite was prepared by a template method implying the polymerization of cholesteric mixture containing of several components. UV light action induces E-Z isomerization of the azobenzene-containing molecules of photochromic mixture and decrease in their molecular anisometry leading to isothermal phase transition from LC to isotropic state or decrease in LC order degree. Both electro- and photo-induced changes are completely reversible and switching the electric field off and/or irradiation with visible light completely recovers initial shape of selective reflection band. The observed switching is very fast and takes several seconds for the light action and less than one second for the electric field.n
