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.
Incorporating 2% of the UV-curable polymer monomer into the liquid crystal material allows for pretilt alignment of the liquid crystal molecules by applying a suitable electric field perpendicular to the substrate while polymerizing it, and by controlling suitable curing conditions And the curing electric field, any pretilt angle from 0 ° to near 90 ° can be obtained.The mechanism of the interaction between polymer and liquid crystal molecules is described in detail in this paper, and the size of the formed pretilt is analyzed and calculated. The paper gives a more detailed calculation formula and calculation results.
