Abstract(in English) | The morphology of fine polymer network formed in ferroelectric liquid crystal was observed with an optical microscope and a scanning electron microscope, and its formation mechanism was studied for obtaining the rigid polymer network supporting substrates of the liquid crystal devices. It was found that the polymer made from mono-functional acrylate monomer by photopolymerization-induced phase separation forms a small fiber morphology with fibril aggregation, which is aligned in parallel to the liquid crystal molecular orientation controlled by alignment layers. The polymer fiber became stout with the increase of the monomer concentration. The self-assembling phenomenon is considered to be induced by the interfacial tension of liquid polymer component in polymerizing, and the transient morphology of polymer in phase separation process is rapidly fixed by the polymer curing. By forming the aligned polymer fiber network, the spatial grayscale capability was obtained due to the polydomain structure of liquid crystal, and high contrast ratios over 100:1 are achieved for each primary color because of good uniformity of ferroelectric liquid crystal alignment. |
