无取向的高性能液晶智能窗
Non-oriented high-performance liquid crystal smart windows
摘要
Abstract
To address the issues of complex material systems and preparation processes in traditional liquid crystal(LC)smart windows,this study employs negative dielectric anisotropy nematic LC as the base matrix,doped with a cationic surfactant,to fabricate electrically controlled dimming smart window using ITO conductive glass without any alignment treatment.We investigated the transmittance variations of LC smart windows with different doping ratios under an alternating current(AC)electric field across the visible light spectrum.A comparative study on the dimming performance of three LC cell configurations—unaligned,parallel-aligned,and homeotropically aligned(vertical),revealed that the unaligned LC cells outperform the other two alignment structures.The proposed LC smart window achieves reversible switching between transparent and hazy states via ion turbulence induced by the alternating electric field.Within the visible light spectrum,the optical transmittance decreases by approximately 60%.The rise and decay response times are 31.92 ms and 88.01 ms,respectively.Requiring no alignment treatment,this device features a simple structure and is facile fabrication,offering a novel solution for the industrial application of low-cost smart windows in buildings.关键词
