聚合物稳定蓝相液晶的取向控制与电场调谐
Orientation control and electric field tuning of polymer-stabilized blue phase liquid crystal
摘要
Abstract
Blue phase liquid crystals(BPLCs),as self-organized three-dimensional photonic crystals,have demonstrated broad application prospects in tunable photonic devices and spectral modulation.To broaden their range of reflection,we propose an electrically tunable polymer-stabilized blue phase liquid crystal(PSBPLC)system and validate it through theoretical analysis and experimental characterization.First,uniform monodomain BPLC is obtained via photoalignment,followed by photopolymerization to form polymer networks,thereby enhancing the structural stability.Subsequently,by applying a direct current(DC)voltage upon the liquid crystal cell,lattice deformation is induced,enabling wide-range tuning of the reflection spectrum.Furthermore,optical phase information is encoded into the orientation distribution of liquid crystal molecules,enabling holographic display applications via patterned alignment of PSBPs.Results indicate that,under the influence of DC electric field,the central wavelength of the reflection spectrum can be reversibly tuned from 439 nm to 662 nm.The corresponding reflective holographic phase design can reconstruct color images across the visible spectrum.This work provides a viable approach for developing stable,electrically tunable materials with a broad reflection range,showing promising potential in fields such as information display,optical encryption and photonic devices.关键词
