研究了取向剂聚酰亚胺上摩擦强度与液晶的表面锚定强度的关系,分析了液晶的表面锚定强度与液晶分子表面预倾角的关系,并运用空间相互作用模型及表面沟槽理论进行了对比分析,认为液晶分子的表面排列机理主要是聚合物与液晶分子的空间相互作用力。
The relationship between the rubbing strength of polyimide and the anchoring strength of liquid crystal was studied. The relationship between the anchoring strength of liquid crystal and the pretilt angle of liquid crystal molecules was analyzed. The spatial interaction model and surface groove theory The comparative analysis shows that the surface alignment mechanism of the liquid crystal molecules is mainly the space interaction force between the polymer and the liquid crystal molecules.
