Abstract

We have analyzed the micro-phase separation during photo-polymerization in the liquid crystal/polymer composite films for a variety of light-control applications. The photo-polymerization induced phase separation process is remarkably affected by the reactivity in diacrylates and the fraction volume in liquid crystals. It is presumed that the nematic transition in a liquid crystal-rich phase and the reactivity play an important role to determine the morphology.
