摘　　要：在液晶材料中掺入2%的可紫外光固化的聚合物单体,聚合的同时,在垂直于基片方向上施加一个合适的电场,可以实现液晶分子的预倾排列.通过控制合适的固化条件和固化电场,可以得到从0°到接近90°之间任意的预倾角.本文较详细地阐述了聚合物与液晶分子的相互作用机理,并且对于所形成的预倾角的大小进行了分析计算.文中给出了较详细的计算公式和计算结果.Doped with 2% of a UV-cureable diacrylate monomer in a nematic liquid crystal, applied a electric field across the cell during polymerizing, a polymer stabilized pretilt angle of LC molecule can be obtained. The pretilt angles range from 0?to near 90?when we control the suitable polymerizing conditions and appropriate polymerizing electric field. This new orientating method of liquid crystal molecule with polymer network maybe contribute to practical productions in a foreseeable future.
