“…Depending on the concentration of the polymeric materials in the LC matrix a variety of network structures can be created. In recent years, efforts [3][4][5][6] have been made to investigate the influence of polymer network in LCs molecules. Raina et al [3,4,6] have carried out measurement of photo luminous (PL) and electro-optical parameters of LC-PC system.…”

In this work, we have reported the temperature dependence of birefringence for pure liquid crystals (LCs) and liquid crystal-polymer composite (LC-PC) systems. The enhancement of the electro-optical performances is higher in LC with poly (n-butyl methacrylate) polymer. The temperature dependence of the birefringence (Δn) were determined from the transmitted intensity. Dielectric study of pure LC system and LC-PC system has also been presented as a function of frequency. The observed results may be attributed to the occurrence of polymeric domains (chains) formed in LCs. The complete study reveals that the use of polymeric materials in nematic LCs is effective to improve the response in phase shifters devices.

“…Интерес к композитным средам на основе ЖК связан, в первую очередь, с их научным и техническим потенциалом [1]. Была показана возможность электроуправляемого рассеяния наночастицами в ЖК-матрице [2], создания электроуправляемых переключателей [3] и плаз-монных цветофильтров с подстройкой цвета в зависимости от приложенного напряжения [4], улучшения динамических [5] и электрических [6] характеристик ЖК-сред для дисплеев, а также создания 3D экранов [7].…”

Effects of polymer doping on dielectric and electro-optical parameters of nematic liquid crystal

et al. 2014

View full text Add to dashboard Cite

Poly(isobutyl methacrylate) (PiBMA) polymer doped in pure p‐Ethoxybenzylidene p‐Heptylaniline (EBHA) mesomaterial has been investigated in the present study. The dielectric and electro‐optical parameters of EBHA having nematic phase were altered due to the addition of polymer in different concentration. The strong dopant concentration dependent nature of negative dielectric anisotropy and conductivity are the interesting results of the present polymer doped nematic liquid crystal (NLC) system. The present composite shows its useful application in low charge consumable devices due to the easy charge transportation phenomenon. The investigated polymer doped‐NLC system exhibiting increased negative dielectric anisotropy and high conductivity may prove to be advantageous for video applications in vertically aligned cells.
