The electro-optical performance characteristics of polymer dispersed liquid crystal (PDLC) were investigated with the addition of organized clay minerals. In the case of an organized clay having good affinity for the liquid crystal, the organized clay was dispersed homogeneously in the liquid crystal in the size of several micrometers. With the addition and increasing amount of the organized clay, the contrast between the light scattering and transparent memory state was increased due to the high affinity for liquid crystal. Also, it was founded that PDLC based on liquid crystal containing organized clay showed that the memory effect exhibited by the liquid crystal/clay (LCC) is rather unusual since most of conventional nematic liquid crystals do not exhibit such a memory effect due to their low viscosity. |
