The electro-optical property of guest-host PDFLC film containing anthraquinone dye
This paper focuses on the light transmission properties of Dye Guest-Host Polymer Dispersed Ferroelectric Liquid Crystal (DGHPDFLC). The DGHPDFLC samples were prepared by using various concentrations of UV curable polymer and 3 wt% blue dichroic dye under various intensities of ultraviolet irradiation. This system can remove a polarizer to achieve better brightness, and improve the transmission of Dye Guest-Host Ferroelectric Liquid Crystal and Polymer Dispersed Ferroelectric Liquid Crystal systems. The results show that the addition of polymer increases the ratio of transmitted light. The prepolymer (NOA65) become fully cured at a higher UV irradiation intensity, and it decreases the transmission of the system.
