We have investigated the photo polymerization induced phase separation process in liquid crystal/polymer composite films. The differences of morphology depending on the type of diacrylate are observed with SEM microscopy. Obviously, the shape of the polymer phase is sensitive to the molecular structure in diacrylets. In the confocal laser microscopy, it is turned out that the behavior on the nematic domains in the kinetics of phase separation can be distinguished by the type of diacrylate. In the HDDA and the C2000, the faster nuclear growth rate and the frequent coalescence of neighboring nematic domains accelerate the growth of LC domains. In the AE-67, the nematic domains at 1 μm continue to gradually grow with a slight coalescence. It is presumed that the kinetics in the phase separation process play a important role to determine the morphology. This work was performed under the management in ASET project supported by NEDO.
