Abstract： |
The invention discloses a material to improve the LCD-oriented directional optical properties fabrication methods, which belongs to photosensitive materials technology. The photosensitive materials are mixed of epoxy resin-based materials and polymer-oriented materials. Those two containing materials corporations are cinnamoyl cyclization reaction, thereby induced liquid crystal alignment. The material for the preparation methods is to replace the benzene ring cinnamic acid and slightly excessive thionyl chloride and so on the benzene ring completely replace the cinnamon chloride solution Solutions to increase with the acid absorbent polar aprotic solvents, phenol or two polyphenol solution drop wise, be used doped photosensitive materials, photosensitive materials to be epoxy-based polymers for optical orientation of mixed-orientation was obtained material. This invention can improve LCD-directional capability of a single polymer-oriented material, and also achieve proper optical directional effects by choosing the type of photosensitive materials and the ratio of them. |
