Abstract:Because the temperature directly affects the viscoelasticity and dielectric coefficient of the liquid crystalline materials, and then affects the driving performance, it is necessary to study it deeply. A new thermotropic liquid crystalline material 82832 was selected as the research object, and the temperature range of the 82832 was determined from 48 ℃ to 118 ℃ by DSC test. Taking 50,60,70 ℃ as the driving temperature, and the twist angles of 0°, 45°,90° as the basic variables, the driving performance of 82832 was studied. The results show that the driving speed increases with the increase of the driving voltage, and the maximum driving speed is obtained when the temperature is 60 ℃ and the torsion angle is 0°;by changing the applied driving voltage frequency, the driving effect is verified again, and the optimal driving temperature is 60 ℃ and the optimal driving frequency is 10 Hz. On the basis of the previous research, the numerical model of liquid crystal 82832 was established and the theoretical calculation was carried out, and the results were in good agreement with the experimental results. The results provide reference for the application of the liquid crystalline backflow micro-driving.
