A PSCOF cell under an optical microscope with crossed polarizers, LC molecules are homogeneously aligned along the rubbing direction . (a) Bright state: is at 45° to the fast axis of the polarizer; (b) dark state: is parallel to .
Schematic diagram for the formation of PSCOF structure. (a) Diffusion of small molecules caused by nonuniform polymerization. (b) The bilayer structure of a PSCOF cell after phase-separation.
SEM pictures of polymer layers formed in PSCOF cells. The polymer content was (a) , (b) , and (c) . The thickness of the polymer film monotonically increased from as the polymer content increases.
Experimental setup to measure the transmission as a function of applied voltage and the results for cells with the and LC.
Sectional SEM view of a PSCOF cell with LC shows a uniform gap of formed between the polymer layer (bottom) and the substrate with rubbed PI film (top).
The optical transmission vs time (channel 1) under a rectangular-wave pulse (channel 2) with amplitude of (a) , and (b) for cells with and LC.
