Demonstrates improved electro-optic properties in liquid crystal devices using SNW-PVDF alignment layers, suggesting significant advancements in display technology.
This study focuses on the development and analysis of polyvinylidene fluoride (PVDF) alignment layers enhanced with silver nanowires (SNWs) to improve the electro-optic properties of liquid crystal (LC) devices. Optical characterization using UV-Vis spectroscopy showed that all SNW-PVDF films maintained high transmittance (~85–86%), suitable for display applications. Atomic force microscopy (AFM) confirmed stable surface morphology with no significant disruptions from SNW inclusion. Electro-optic analysis revealed a reduction in threshold voltage and improved response times, particularly for films with lower SNW concentrations. Finite element method (FEM) simulations highlighted the mechanism by which SNWs enhance local electric fields (~1.5×) near alignment layers, facilitating faster LC driving. Additionally, SNWs mitigated hysteresis effects observed in the voltage-capacitance curves, contributing to device stability. These findings demonstrate that SNW-PVDF alignment layers provide an effective pathway for enhancing LC device performance, offering advancements for electro-optic applications.
