预取向液晶单体光聚合反应

In-Situ Photopolymerization of Oriented Liquid-Crystalline Monomers

通过表面摩擦、施加外电场(或磁场)和应力剪切等手段使液晶单体取向后进行光聚合反应是制备高度取向、高度均匀和高度透明高分子液晶膜的重要方法。它在高分子非线性光学材料、导电商分子材料和光纤涂层等领域中具有广泛的应用前景。

The photopolymerization of polymerable liquid-crystalline monomers criented by surface treatments, electric and/or-magnetic fields, application of shear stress is an importment method for preparing highly homogeneous, hihgly transparent and highly oriented polymeric liquid-crystalline films, which is prospective in the applications such as nonlinear optical materials, electrical conductive materials and optical fiber coatings.
