What is the value of the rotational viscousity of (Merck) E44 Liquid Crystal? How E44 depends on the voltage? I need to know these parameters for the experiment. Thank you in advance!
chances are the value of rotational viscosity for this liquid crystal has not reported in the literature, and even if it has, it might not be at the temperature you are interested in. Therefore, I have attached the info about the technique through which you can measure the rotational viscosity of any liquid crystal.
Do you want to know how its retardation or birefringence depends on voltage? or the threshold voltage?
There's a lot of information on the E44 LC, including rotational viscosity. Measurements were done in the magnetic field + relaxation times and dynamical properties
