Polymerization Induced Phase Separation

Polymer dispersed liquid crystal film was prepared by the method of polymerization induced phase separation. The optical morphologies of the PDLC film were characterized by polarized optical microscope with a hot stage. Our results demonstrated that the morphology of the PDLC film depended on temperature of PDLC system.

Polymerization Induced Phase Separation

ABSTRACTWe 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.

Polymerization Induced Phase Separation

Polymer dispersed liquid crystal device was prepared by the method of polymerization induced phase separation. The phase separation in our PDLC device was characterized by a polarized optical microscope. Our results demonstrated that the phase-separated droplets in our PDLC device presented the four-brush radial, bipolar and axial configurations. Furthermore, these configurations were simulated by mathematica tool
