Dielectric anisotropy in liquid crystal mixtures with nematic and smectic phases

doi:10.1088/1674-1056/ad4cd7

Abstract The modulation of dielectric anisotropy ($\Delta \varepsilon $) is pivotal for elucidating molecular interactions and directing the alignment of liquid crystals. In this study, we combine liquid crystals with opposing dielectric anisotropies to explore the impact of varying concentrations on their properties. We report the sign-reversal of $\Delta \varepsilon $ in both the nematic and smectic A phases of these mixed liquid crystals, alongside a dual-frequency behaviour across a broad temperature spectrum. Our research further quantifies the influence of mixture ratios under various temperatures and electric field frequencies. This exploration may pave the way for the discovery of new physical phenomena.
