Dielectric and electro-optical studies of glycerol/ferroelectric liquid crystal mixture at room temperature

Abstract

The optical memory effect based on glycerol mixed deformed helix ferroelectric liquid crystal ͑DHFLC͒ material has been investigated. The observed memory effect has also been compared with the glycerol mixed ferroelectric liquid crystals ͑FLCs͒. The observance of memory effect has been verified by experimental data using dielectric spectroscopy, electro-optical, and textural studies under polarizing optical microscope. The glycerol not only helps to improve the memory effect in DHFLC material but also alters the physical parameters such as rotational viscosity, spontaneous polarization, response time, etc. too in both glycerol/DHFLC and glycerol/FLC mixtures.

Equimolecular Mixture of Calamitic and Bent-Core Thiobenzoates

“…5%. 3. Results and discussion Figure 2 shows the phase situation of the equimolecular mixture of MHOBS8/IFOS8 (EM) in the comparison of calamitic liquid crystals.…”

“…Recently, the researchers have been vividly interested in mixtures characterized by ferroelectric properties (e.g. [3,4]), and especially in the mixtures of bent-core and calamitic liquid crystals, in which an equimolecular binary mixture are the important object of the investigations (e.g. [5][6][7][8]).…”

Nematic liquid crystal/dimethylsulphoxide mixture based tuning condenser

“…The impact of LC on modern technology such as a biosensor, memory devices, LC-based lasers, holography has been profound [8,9]. Besides these modern familiar applications, there are other devices with improved properties of LC by doping nanoparticles or mixing with other inorganic/organic solvents as LCs are favorable material for the effective transfer of ions and electrons [6,[10][11][12][13].…”
