摘要
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 relation between the liquid crystal surface anchoring strength and the rubbing strength on polyimide was investigated. The relation between the anchoring strength and the surface pretiit angle of liquid crystals was analysed, and it was theoretically explained by a steric interaction model. The steric interaction between polymer and liquid crystal molecules is dominant in determining the surface orienta-tion of nematic liquid crystals.
