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.

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

Polymerization Induced Phase Separation

Polymer dispersed liquid crystal (PDLC) devices were prepared by the method of polymerization induced phase separation. The transmittances and textures of the PDLC devices in OFF state and ON state were characterized by an ultraviolet-visible spectrometer and a polarized optical microscope, respectively. Our results demonstrated that the transmittances of our PDLC devices can be up to 95% when it is in ON state and that the transmittances of our PDLC devices is only about 20% when it is in OFF state.
