Abstract
We designed the novel experimental method to measure the conductivity and transmittance of polymer dispersed liquid crystals simultaneously during polymerization-induced phase separation process. The rate and conversion of polymerization, degree of phase separation of liquid crystals and formation of nematic microdomains can be measured simultaneously. Using this experimental method, we investigated the influence of content of liquid crystal on polymerization and phase separation process. The experimental results showed that, as the liquid crystal content increased, the interval between the starting point of phase separation and the ending point of photopolymerization increased, indicating an increase in the size of microdomain. This noble in-situ measuring technique has been proven to be reliable and effective in monitoring the gelation process of polymer dispersed liquid crystal system, and subsequently provides new possibilities for evaluating the phase separation behavior of polymer dispersed liquid crystal system.
