“…24 The dielectric studies of glycerol have been performed by several groups earlier. [24][25][26] The temperature dependence of the quasistatic dielectric permittivity of highly viscous glycerol has also been discussed. 25 Figure 1 shows the dielectric permittivity and dielectric loss factor of glycerol as a function of frequency at different applied voltages.…”

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.
