Abstract

Dielectric properties of both in-phase and anti-phase motions of polymer-dispersed antiferroelectric liquid crystals (PDAFLC) were changed because of the influence of charge density accumulated on smectic layers and its gradient variation. The elastic constant as well as dielectric parameters were changed because of the coupling between charge density variation and the physical properties of polymer constituents such as free volumes, cross-link chains. The theoretical model provides a clear influence of charge density in PDAFLC which modified the dielectric parameters, such as dielectric constant, dielectric loss, dielectric strength, etc. depending on the variation of charge density as well as polymeric parameters for both in-phase and anti-phase motions. The obtained theoretical basis is discussed by considering the results with the experimental findings and the theoretical deduced equations.
